| 摘 要： | 针对上海轨道交通15号线某车站基坑条形且超长的特点，在承压水控制设计中充分利用了非对称帷幕下的短滤管三维流及基坑分坑的尺度效应进行承压水控制设计，分析了非对称帷幕下的渗流规律和不同降水运行方案下的环境影响，综合工期、资源配置和降水预测分析，最终确定了相对最合理的运行方案。

| Abstract: | Aiming at the characteristics of the strip-type and overlong foundation pit of a station in Shanghai Metro Line 15, the three-dimensional flow of short filter pipe under the asymmetric curtain and the scale effect of foundation pit sub-pit are fully utilized in the design of confined water control. The seepage rule under the asymmetric curtain and the environmental influence under the different precipitation operation schemes are analyzed. The most reasonable operation scheme is finally determined by integrating the construction period, resource allocation and precipitation prediction analysis. |
