Gate seismic response analysis method considering gate water seal mechanical property effect

Abstract

The invention relates to a gate seismic response analysis method considering the gate water seal mechanical property effect. The gate seismic response analysis method comprises: S1, determining the relation and a friction coefficient of a water seal compression modulus along with the compression amount; S2, determining a structural body type of the water seal; S3, determining the pre-pressing amount of the water seal; S4, determining the relation between the water seal pre-pressing amount and the width of the water seal contact face; S5, building a spring model for connection between the gateand the dam body or between the gate and the gate pier; S6, determining the acting force applied to the unit length of the water seal; S7, determining the total acting force acting on the water seal;S8, establishing a gate three-dimensional geometric and finite element model; S9, establishing a gate structure mechanical equation; and S10, inputting corresponding seismic fluctuation data, and calculating the seismic response of the gate structure. According to the gate seismic response analysis method considering the gate water seal mechanical property effect, the problems that an existing method neglects the influence of a gate auxiliary water seal structure and connection and seismic force transmission between a gate and a dam body can be effectively solved.

Description

technical field [0001] The invention relates to the technical field of gate seismic response analysis, in particular to a gate seismic response analysis method considering the mechanical characteristic effect of the gate water seal. Background technique [0002] Hydraulic steel gate is a common type of water retaining structure in hydraulic structures, and it is also an important control structure in engineering. It is mainly used for flood discharge, water diversion, sand discharge control and power station accident control of water conservancy projects. In the design of hydraulic steel gates, static design is mainly used, considering the importance of the project, and a dynamic safety factor of 1.2 times is considered on the basis of static design; in areas with high earthquake incidence and seismic intensity higher than 7°, the gate needs to be repaired. Anti-seismic design. The method used in the seismic design of the gate generally adopts the quasi-static method, and t...
