Seismic characteristic research of hydraulic plate gate

The paper first elaborates the analytical method of seismic response of hydraulic plate gate, and then analyses the seismic response of release gate under the general water-retaining condition by the method of the seismic wave acceleration-time process curve. The result indicates that when the fortification intensity of earthquake is eight degree, dynamic stress and displacement of gate are much more than specified value of discipline, which states that the probability of seismic damage of gate is very high. On the basis, the paper modifies the gate according to the requirement of seismic design, approving the seismic capability. The research guides the seismic safety design of hydraulic plate gate.
