水泥土搅拌桩复合地基承载力的确定

Determination of bearing capacity for composite foundation of cement-soil mixing piles

摘要

摘要: 在水泥土搅拌桩复合地基设计中,复合地基承载力是最重要的设计依据。本文通过对多个搅拌桩工程的单桩和复合地基载荷试验结果进行分析,发现工程中的水泥土单桩的实际承载力一般难以达到设计或理论计算值。在此基础上,对工程中如何确定水泥土搅拌桩复合地基承载力特征值提出了一些合理化建议。

Abstract: It is very important to reasonably determine the bearing capacity for composite foundation of cement-soil mixing piles in composite foundation design. The bearing capacity relationship between the cement soil pile and the composite foundation is studied through many field bearing tests.The test results show that the field bearing capacity of single cement-soil pile is lower than the theoretical value.Some rationalization proposals are presented based on the test results.
