Analysis of the effectiveness of anti-seepage treatment for the Chengang new station pressure relief well
In order to analyze the pressure-reducing performance of relief wells as permanent wells in pumping station forebay,Chengang new station was used as a research object.The seepage stability of the foundation with different relief well arrange-ments was simulated,compared and analyzed,including single-row wells,double-row wells,the combined application of double-row wells and cement-soil replacement.The results showed that the combined application of double-row wells and cement-soil replacement had significant pressure-reducing performance,which was conducive to seepage stability and anti-sliding stability of the foundation,and could provide the design reference for the similar pumping stations.
