| 摘 要： | 施工开挖对土体产生卸载作用,坑壁及坑底土体的应力状态和应力路径发生变化.就基坑边坡整体滑动稳定性计算所采用的圆弧法提出问题,根据卸载土体的不同状况设计二组快剪试验方案,并对其加载、卸载过程的强度特征进行试验研究.试验结果表明,土体的卸载强度与加载强度存在差异性,为完善基坑边坡稳定计算方法提供依据.

| Abstract: | Different unloading effects in construction occur to the surrounding earth.As a result,the stress state and stress path of the soil at sides and bottom of pit are changed.The question is brought forward according to the arc method which is used to calculate the stability of foundation pit slope in the beginning of this paper.A series of laboratory tests are designed according to different states of disturbed soil in order to study the characteristics of strength during the course of loading and unloading.The test results show that the behaviors of strength under unloading paths are much different from those under loading paths.The purpose of this paper is to improve the method of calculating the stability of foundation pit slope. |
