| 摘 要： | 针对同时考虑作用在水体上的粘滞力和作用在土体上的渗透力这一特殊工况，建立微分平衡方程，求解得到计算水-土压力公式。以深基坑典型支护结构(止水帷幕+支护桩)处理方式作为研究对象，基于土拱理论推导出考虑渗流影响的深基坑支护桩桩间距计算式，并结合工程实例计算出考虑渗流影响的深基坑支护桩桩间距。

| Abstract: | Considering viscous force and penetration power on soil mass at the same time,differential balance equation is established to obtain the formula of water-soil pressure.In this paper,taking typical supporting structure(waterproof curtain + supporting pile) of deep foundation pit for example,the formula of the space of deep foundation pit supporting pile considering seepage is educed based on soil arch theory.And the space of supporting pile considering seepage is calculated combined with engineering example. |
