Structure Seismic Analysis on Intake Tower of Spillway Tunnel

Abstract

According to a intake tower of spillway tunnel established the intake tower structure—water—foundation 3-D finite element model for seismic analysis, by the response spectrum method in original design seismic parameters and new parameters of the project on horizontal and vertical dynamic response of the intake tower. The results shown that the structure of maximum dynamic stress concentration appeared near the junction of the tower with backfill concrete, where the weak parts of seismic, used the new seismic parameters calculated show greater damage on the tower, but couldn’t overturn, meet the seismic design requirements.
