| 摘 要： | 指出在开挖软土基坑时,如桩后的土柱重量超过基坑地面以下地基承载力时,地基平衡状态将受到破坏,就会发生坑壁土流动,坑底下陷、隆起的现象,此时应验算坑底土的抗隆起稳定性,提出充分考虑桩脚处主被动土体对抗隆起的影响的计算方法,并结合工程实例,对该方法进行了检验,说明了同其他方法相比的合理性。

| Abstract: | The paper points out the balance of the foundation will be damaged,and the soil on pit s walls will flow,the bottom will fall and heave in the excavation of the pit,when the earth column s weight is larger than the foundation s loading capacity below the foundation,so the resistant heave s stability should be calculated,indicates the calculation methods of the weight of the active-passive earth on the resistant heave,and tests the method,so as to indicates its reasonability. |

| Keywords: | deep foundation pit heave anti-sliding moment sliding moment safety parameter |
