摘　　要：地质条件对泵站地基处理设计影响较大,以沿江某泵站为例,针对泵站处复杂地质条件进行分析,结合工程特点,经过方案比较,采用塑性混凝土围封墙解决了渗透稳定和砂土液化问题,利用钉型水泥土双向搅拌桩+换填复合地基对地基进行加固处理,效果良好,可为类似项目设计提供参考。Geological conditions had a significant impact on the design of foundation treatment for pump stations.Taking a pump station along the Yangtze River as an example,this paper analyzed the complex geological conditions at the site of the pump station.After comparing different options and considering the engineering characteristics,a solution was proposed,which utilized a plastic concrete perimeter wall to address the issues of permeability stability and sand liquefaction.In addition,a combination of soil nailing cement and two-way mixing piles and replacement composite foundation was used to reinforce the foundation.The results were satisfactory,and this solution may serve as a reference for similar projects.
