Dynamic Response Analysis of Intake Tower-Hydrodynamic Coupling Boundary Based on SV Wave Spatial Incidence

In view of the insufficient analysis coupled joint seismic response intake tower–reservoir water–foundation boundary under oblique incidence SV wave space, a three-dimensional dynamic equation space is established in this paper. The external input method viscoelastic artificial combined with equivalent load and acoustic medium theory are used to simulate action reservoir water, angle change realized by controlling incident vector. structure analyzed characteristics at different angles discussed. results show that damage degree tower decreases first then increases angle. When vertical 0°, maximum displacement drop 82.05%, more sensitive vertically 0° 35° (near critical incident), response, water pressure, diffusion velocity, area, relatively large, which seriously affects safety stability tower. Therefore, influence should be considered comprehensively aseismic design provide new idea for evaluation same type engineering.
