摘　　要：深层搅拌桩在极限承载力确定方面,工程人员的成熟经验对承载力的确定有非常重要的意义。将深层搅拌桩极限承载力看作模糊变量,上部荷载作为随机变量,讨论了模糊变量与随机变量相结合时的可靠度计算问题。提出了深层搅拌桩承载力的隶属函数和上部荷载作用下复合地基安全承载的隶属函数的确定方法。结合工程实例计算,证明了该方法合理性和实用性。The mature experience of technical personnel is important to determine the ultimate capacity of Dry-jet Mixing composite foundation.the ultimate capacity of deep mixing is taken as fuzzy variable and upper structure load is taken as random variable,the problems of reliability calculation is discussed when fuzzy variable and random variable are combined.Determining membership function methods of ultimate capacity and safety carrying load are put forward.The rationality and practicability of this method has been approved with the real project calculation.
