某工程水泥土搅拌桩复合地基设计及检测实践

摘要

Through analyzing the engineering geological condition of the first level land in the north of Beisha River, it carries on foundation treatment by using cement-soil mixing pile composite foundation. Through drilling coring, it does non-side-limit compression strength experi- ment, carries on detection and static load test for the pile quality density, continuity and uniformity, and determines the characteristic value of composite foundation bearing capacity. In the end, it finds oat the design narameter of cement-soil mixin~ nile cornrm~ite fot]nrl~tinn%通过分析北沙河北岸一级阶地某工程地质条件，提出了用水泥土搅拌桩复合地基设计进行地基处理。同时通过钻孔取芯做无侧限抗压强度试验对桩体质量密实度、连续性、均匀性进行了检测和静载荷试验，确定复合地基承载力特征值，最后得出水泥土搅拌桩复合地基设计的参数。
