The department of geotechnical engineering and the research school of geotechnical engineering are composed of the institute of tunnel and underground engineering, the institute of soil and foundation engineering, the institute of urban engineering geology and environmental geology, the experimental center for geotechnical engineering and the harbor, waterway and coastal engineering division. The experimental center is established on the basis of the former soil mechanics and foundation engineering laboratory, soil dynamics laboratory, engineering geology laboratory and underground structure laboratory. This center provides service for the three institutes and one division of the department and the school as well as other social sectors who need help.
As a state and provincial key discipline and assisted with the financial aid from the ministry of education and the provincial government, the experimental center is further equipped with the biaxial rock creep testing system, triaxial system for unsaturated soil testing, continuous surface wave system and creep test cell for soil ú. The biaxial rock creep testing system can be used to do shear creep test of rock and concrete apart from the conventional uniaxial and biaxial rock creep and relax .The continuous surface wave system is the first of its type in China, which is fully controlled by computer. It can be utilized to test the wave speed and hardness of soil on the spot of construction and provides fast and undisturbed soil testing for all layers of soil, which plays a very important part in forecasting foundation subsidence. These instruments and equipment have been employed in such state and provincial major projects as Rongyang Bridge. In addition, we are now engaged in an international cooperation on an unsaturated soil testing project with France and Belgium.
We have 2 professors, 1 associate professor and more than 10 engineers and laboratory technicians, among which 3 are PhDs. The center is composed of the geology and rock and soil mechanics teaching laboratory, geotechnical simulating laboratory, soil dynamics testing laboratory, rock mechanics testing laboratory, rock mechanics micro-analysis laboratory, in-situ testing and monitoring laboratory, harbor engineering laboratory, underground structure and model laboratory, geotechnical examination and soil laboratory.
The research focuses of the center include rock and soil creep, soil dynamics, the research on soil(rock)constitutive model, geotechnical model testing research, on-the-spot geotechnical monitoring techniques and so on.
