The Lab of Large Trixial Earthquake Simulating Shaking Table is equipped with the domestically and internationally advanced trixial earthquake simulating shaking table with 6 degrees of freedom. With large table size, big load capacity, and wide working frequency range, the shaking table is reputed as the world’s best experiment equipment for dam by the internationally renowned experts. A number of analysis programs for the gravity dam and static/dynamic of arch dam have been developed in the laboratory. These programs have been certified by the national metrology authorities, and granted with A-class national seismic risk assessment qualification certificates. Its members have edited the Specifications for Seismic Design of Hydraulic Structures, which is jointly issued by the State Power Corporation of China and the Ministry of Water Resources, and participated in the preparation of other five national and ministerial norms and standards.
The lab is also engaged in the seismic studies in many fields, such as the earthquake resistance of the power station and its key equipment; key technologies of the anti-earthquake and seismic isolation for long-distance water conveyance project structure; earthquake resistance and seismic absorption measures for the large-scale civil engineering, underground structures and high-rise buildings; dynamic performance of full-graded mass concrete, and so on.

The main purpose of the test is to study the dynamic performance of the dam, the dynamic stress distribution of the dam during earthquake, the transverse joint aperture of the dam, and interaction of the dam and reservoir water.
It is a 3D nonlinear seismic response analysis for the arch dam system, which takes into consideration the actual geological and topographical conditions in the dam area, the infinite foundation radiation damping and the impact of the contraction joints of dam. On the trixial earthquake simulating shaking table with 6 degrees of freedom, conduct the similar dynamic model test, which takes into consideration the infinite foundation radiation damping, the impact of the contraction joints of dam, the simulation of dynamic interaction between reservoir water and dam, and the embodiment of the dam tensile strength.
The main purpose of the test is to study the dynamic characteristics, the dynamic deformation and fracture distribution conditions during earthquake, as well as the dynamic stress value and the weak parts in structure design of high-rise buildings.
he main purpose of the test is to study the dynamic characteristics, the dynamic stress value and the weak parts in structure design of the television tower; the upper equipment level section size and reinforcement quantity have been improved through experiment, and the seismic capacity has been accordingly enhanced.
The purpose of the test is to study whether the rod-drop function of the key equipment-control rod drive mechanism in nuclear power station is normal during earthquake, and ensure the mechanism’s integrity is not destroyed by earthquake, etc., so as to guarantee the seismic safety performance of the nuclear power station.
