Outline of the Website of Each Research Laboratory

Structural Analysis Laboratory

		Yoshimi Sonoda, Professor Mituteru Asai, Associate Professor Hiroki Tamai, Assistant Professor

		Currently, through the use of computer-based numerical analysis, we are studying techniques to verify structural performance: this is necessary to ensure the safety and security of public structures.

Structural and Aesthetic Design Laboratory

		Shinichi Hino, Professor Shigenobu Kainuma, Associate Professor Akihiko Higuchi, Associate Professor Kohei Yamaguchi, Assistant Professor

		Our studies can broadly be categorized into two fields of engineering: The first is “structural engineering,” which deals with themes such as the construction of safe and comfortable social infrastructure for the future and the diagnosis of existing social infrastructure and the development of social infrastructural maintenance management systems. The second is “landscape engineering,” which aims to create beautiful national lands and communities.

Earthquake Engineering Laboratory

		Hisanori Otsuka, Professor Yukihide Kajita, Associate Professor Joon-Ho Choi, Assistant Professor

		In highly advanced and complicated urban cities, it is essential to enhance disaster prevention abilities in order to create a safe living environment. Earthquake disasters are highly dependant on the vibration characteristics of structures as well as on the characteristics of seismic movement. In order to reduce earthquake disasters, it is indispensable to be able to predict and understand expected disasters and the execution of appropriate design. In this laboratory, we deal with a wide range of themes, including prediction of seismic movement, enhancement of seismic design methods for civil structures (bridges, in particular), and development of seismic-resistant and seismic-isolation design methods.

Concrete Laboratory

		Hidenori Hamada, Professor Yasutaka Sagawa, Associate Professor

		The main subject of our study is “concrete,” which is one of the materials used to create infrastructure that supports our daily lives and economic activities. In order to construct concrete structures that are safe, durable, and in harmony with the natural environment, we are studying durability evaluation and recycling methods for materials. We are also engaged in other research themes, such as techniques to diagnose the degree of structural soundness to increase the longevity of existing structures.

Environmental Geotechnology Laboratory

		Yasuhiro Mitani, Associate Professor Hiro Ikemi, Assistant Professor

		Aiming to achieve a harmonious relationship between geospheric (ground surface and underground) development and environmental conservation, we are working on studies such as the forecast of natural environmental changes due to development, techniques to mitigate such changes, effective utilization of underground spaces, ground restoration, methods for monitoring the ground environment, an so on.

Geotechnical Engineering Research Group

		Noriyuki Yasufuku, Professor Kiyoshi Omine, Associate Professor

		Aiming at the advanced utilization of ground space, and in order to safely build structures on various types of ground, we are engaged in the development of ground stabilization techniques, advanced foundation construction technologies, and expert systems.

Geo-disaster Laboratory

		Guangqi Chen, Professor Kiyonobu Kasama, Associate Professor

		In order to construct a disaster-proof city, we are conducting research into the formulation of a standard for seismic measures in public facilities, risk management using disaster prevention systems, liquefaction of the ground, countermeasures to prevent this, etc.

Transportation System Engineering Laboratory

		Tomonori Sumi, Professor Yoshinao Oeda, Associate Professor Chiaki Matsunaga, Assistant Professor

		The prediction of transportation phenomena and behavior based on human behavioral psychology are vital to urban transportation planning; therefore, we are conducting research on methods for prediction and the construction of transportation planning methods as well as on the development of public transportation systems.

Urban System Planning Laboratory

		Kenichi Tsukahara, Professor Satoshi Toi, Associate Professor

		We focus on a wide variety of problems faced in cities, such as declining population and deterioration of the global environment. With an emphasis on local cities, we analyze the realities and structures used to deal with these problems in detail. Based on the analysis, we study solutions and propose policies using analytical methods such as simulation.

Urban and Environmental Engineering Laboratory

		Takahiro Kuba, Associate Professor Kyoko Oishi, Assistant Professor

		“No water, no future!” Water is a very valuable resource, which is why the 21st century is called the century of the water war. The water environment is made up of water quality, water volume, life forms, bottom sediment, waterfront, landscape, etc., all of which should be preserved. In this laboratory, we are conducting research on the integrated preservation of the water environment using various technologies such as water environment purification, integrated water management, and sewage treatment, from a wide range of viewpoints that cover the large scale of urban ecology and the small scale of microorganism ecology.

Watershed System Engineering Laboratory

		Yukihiro Shimatani, Professor Haruyuki Hashimoto, Associate Professor Hironori Hayashi, Assistant Professor

		We are conducting research on flood analysis and disaster prevention methods for disasters such as the Fukuoka City flood and the Minamata sediment damage, the sediment transportation mechanism of the Yellow River in China, the preservation and regeneration of natural river environments, and the regeneration of historical environments.

Environmental Fluid Dynamics Laboratory

		Shinichiro Yano, Associate Professor Hideo Oshikawa, Assistant Professor

		Water is indispensable to all living beings in the natural world, including humans. However, it is predicted that global warming and population explosion will soon lead to the scarcity of quality water resources. There is also speculation about the worrying increase in natural disasters like tidal waves and floods. In the Environmental Fluid Dynamics Laboratory, we are conducting research to establish a technological system that satisfies both preservation of the natural environment and strengthening disaster prevention.

Coastal Ocean Engineering Laboratory

		Noriaki Hashimoto, Professor Akinori Yoshida, Associate Professor Masaru Yamashiro, Assistant Professor Masaki Yokota, Assistant Professor

		The coastal areas of Japan are constantly under threat from natural disasters like high waves, tidal waves, and tsunamis, while these areas are also used for various industrial fields, including logistics, fishing, leisure, and sightseeing. In this laboratory, we are conducting research on the prediction and analysis of natural phenomena like waves and flows. We wish that you will experience the wonder and excitement of this research, which combines field observation, water tank model experiments, and simulation using computers.

Hydrosphere Environment Laboratory

		Yoshinari Hiroshiro, Associate Professor Koji Nishiyama, Assistant Professor

		In this laboratory, we are conducting research on the water cycle and water resources on both a global and a regional scale. From the perspective of the water cycle, our specific research themes are securing water resources associated with urbanization, operation of water resources in drought, a wide variety of effective water utilization methods, artificial rainfall, salination of groundwater, behavior of contaminants of groundwater, construction of a sound water cycle system of surface stream water and groundwater, water and environment problems inside and outside of the new campus, climate and abnormal climate due to global warming, and the prediction of cataracts.

Environment Control Engineering Laboratory

		Takayuki Shimaoka, Professor Hirofumi Nakayama, Associate Professor

		We are conducting research on the construction of a resource recycling social system using the system engineering approach. We are also researching technology for waste treatment to solve geoenvironmental problems.

Ecological Engineering Laboratory

		Satoquo SEINO, Ph.D

		My study area is ecological engineering of the sea shore, rivers and coasts. More specifically, engineering for creating a society that harmonizes the ecosystem and human beings, e.g..: ・conservation and restoration of biological diversity and the habitats of tidal flats and sandy beaches, ・water resource management in river basins and local communities, ・management of fishery grounds, ・environmental planning and assessment.
