夯实水泥土桩复合地基检测中单桩承载力检测的探讨

Discussion of Single Pile Bearing Capacity Detection in the Detection of Rammed Soil-cement Pile Composite Foundation

在目前的工程实践中,夯实水泥土桩在进行单桩静载试验时常出现桩体非正常破坏,导致检测过程中断,单桩承载力无法评价。对此现象进行深入分析,认为造成桩体非正常破坏的原因是由于单桩承载力检测值的确定未充分考虑夯实水泥土强度随龄期的增长规律所致,并对单桩承载力检测方法进行了探讨,对实际工程具有一定的指导意义。

In the process of current engineering practice , non normal failure of pile often occurs in the Staticload test of single pile of the rammed soil-cement pile,which leads to the interruption of the detection,sothat the bearing capacity of single pile cannot be evaluated. In this paper,a deep analysis of this phenome-non is carried out , it is considered that the reasons of the abnormai damage of pile law of the strength of compacted cement soil increases with the curing age has not been fully considered when determining the detection value of single pile,And the testing method of single pile bearing capacity is discussed in this paper,this research has certain guiding significance to the practical engineering.
