某泵站渗透破坏原因分析及处理措施

Seepage Damage Analysis and Treatment Measures of a Pump Station

以某透水砂基上的泵站渗透破坏为例,分析了该站渗透破坏产生的原因,给出了相应的防渗加固处理措施。通过对加固前后地基渗流有限元计算,分析了水位差增加及排水孔封堵对渗流规律的影响,验证了高压摆喷防渗墙在透水砂基泵站防渗处理中的可靠性,可为类似工程提供借鉴。

Taking the seepage failure of a pump station on a permeable sand foundation as an example, this thesis analyzes the causes of seepage damage of this pump station and gives treatment measures. The influence of water level difference increase and drainage hole plugging on seepage law is analyzed through the finite element calculation of foundation seepage before and after reinforcement. The reliability of the high pressure swing spray cutoff wall in the seepage control treatment of permeable sand base pump station is verified.It can provide some reference for similar projects.
