水下干作业复合灌注桩试验研究

Experimental study on dry-bored composite pile under groundwater

简要介绍一种新桩型———水下干作业复合灌注桩的成桩原理与工艺 ,通过试验阐明了其承载力、荷载传递特性、水泥土环桩侧阻力、破坏特性 。

This paper presents the pile forming principle and technique of a new type pile,which is called dry bored composite pile under groundwater. Through field experiments, the bearing capacity and load transfer behaviour, the side resistance and failure characteristic of cement soil ring pile and the effect of strengthening by air for cement soil ring pile after boring of soil core have been described.
