陈岗新站减压井防渗处理效果分析

Analysis of the effectiveness of anti-seepage treatment for the Chengang new station pressure relief well

为分析减压井作为永久井设置在泵站前池的减压效果,以陈岗新站为例,对泵站前池设置单列减压井、双列减压井、双列减压井与水泥土换填结合应用的地基进行渗流稳定模拟与对比分析。结果表明,双列减压井与水泥土换填结合应用的防渗效果显著,有利于站基渗流稳定和抗滑稳定,可为同类泵站设计提供参考。

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.
