摘　　要：从邯郸地区粉喷桩复合地基的工程实际出发,对部分工程的有关单桩及地基土进行了静载荷试验,基于这些试验资料,进行了桩体极限强度及地基土极限承载力的概型分布统计。同时运用可靠度理论研究了本地区粉喷桩复合地基承载力可靠度问题。As the formation of theory system of composite foundation and the development of the reliability on the composite foundation, it makes engineering design more reliable, economical and safe in using the reliability theory on the composite foundation. Based on some DJM pile engineering in Handan, this test presents a solution of reliability parameters with the reliability theory, and analyses the influencing factors of reliability parameters of bearing capacity of composite foundation.
