In order to improve stability of foundation pits against the basal heave failure,a new method called critical width method(CWM)for calculating the factor of safety against basal heave failure was suggested according to Terzaghi s theory of bearing capacity of foundation and considering that only a single-sided sliding surface existed in real cases of failure.
为了提高深基坑抗隆起稳定设计的可靠性,根据Terzaghi地基承载力理论,针对基坑隆起破坏均为单面滑动失稳的实际情况,推导了新的计算抗隆起稳定安全系数方法——临界宽度法,提出了对应抗隆起稳定最小安全系数的临界宽度概念,给出了均质地基的临界宽度的理论解答。
