摘要
鉴于基坑土体稳定性问题同时具有随机性和模糊性的特点,对坑底土体抗隆起稳定性的模糊失稳概率的计算方法进行研究。通过实例计算结果表明:模糊失稳概率将随着模糊过渡区的增大而增大。模糊随机研究方法可以为基坑工程传统的经验安全系数法的安全系数确定提供一定的理论依据。
In view of the random and fuzzy characteristics of excavation soil stability,the fuzzy probability of the bottom of the excavation against heave failure was studied.The example’s results indicate that the fuzzy probability will increase along with the increasing of the fuzzy transition area.The fuzzy-random analysis method can provide a theoretic basis for determining the safety factor with traditional empiric safety factor method of excavation projects.
