| 摘 要： | 用经典的土力学理论计算基坑的水土压力时所得数值和基坑结构上的实测值相差很大，分析了造成这种差异的最重要原因是地下水渗流对基坑土压力的影响，由此提出了考虑地下水渗透力的水土压力计算新图式。该图式对非均质土层基坑工程及边坡工程均适用。通过实例计算表明，根据新计算图式所求得的水土压力值和实测值基本一致。

| Abstract: | Groundwater seepage is explored, which is the main reason why measured water-earth pressure values on supporting structure is generally very different with that calculated with classic earth pressure theories is explored. Mechanical affects of groundwater seepage on earth pressure are studied. A new calculation charts of water-earth pressure on the foundation pit with consideration of groundwater seepage is presented. This calculation chart is universally applicable to the excavation engineering and the stability of earth slopes in homogeneous soil. It is proved that measured water-earth pressure values on supporting structure is consistent with that calculated with the calculation chart. |
