Study on Seismic Risk Reduction and Reinforcement of Homogeneous Dams on Liquefied Foundation in Areas prone to Strong Earthquakes
Due to the lack of a complete seismic system for liquefied foundation homogeneous dams in areas prone to strong earthquakes,the dam body often suffers from earthquake damage.In order to improve the overall seismic performance of the dam body,this article se-lects Xikele Reservoir as the study object and analyzes the causes of earthquake damage.A systematic study is conducted from aspects such as improving the dam body's own seismic resistance,suppressing pore water pressure rise,suppressing pore water lateral flow,and improving water sealing adaptability.An innovative seismic reinforcement method for liquefied foundation earth-rock dams combining sol-id-suppression reinforcement system is proposed.The effectiveness of seismic measures is verified and analyzed using ABAQUS finite ele-ment software.The results show that the adopted seismic system can effectively resist the damage of earthquakes to the dam and buildings.The study has good reference significance for similar projects.
