钻孔桩后压浆技术在工程中的应用

The Application of Bored Pile's Post-mud-jacking Technique in the Engineering

对钻孔灌注桩后压浆技术提高基桩承载力的原理进行了表述,分析了后压浆钻孔灌注桩与普通灌注桩的异同及二者的比例关系,通过工程实践证明,后压浆技术是提高基桩承载力的一种有效方法,是经济可行的。

This paper describes the principle of increasing the bearing capacity of the pile foundation with bored pile＇ s post-mud-jacking technique, analyzes on the similarities and differences of the post-mud-jacking bored pile and the common filling pile and the proportional relation between the two kinds of piles, and through the actual engineering, demonstrates that the post-mud-jacking technique, which is an effective method for increasing the bearing capacity of the pile foundation, is economic and practicable.
