钻孔灌注桩后压浆施工工艺与单桩承载力试验

Application of post grouting technique of cast-in-place bored pile and bearing capacity test of single pile

高层建筑的桩基工程中单柱承载力的大小是影响桩基工程的经济技术指标。本文通过工程实例分析表明,后压浆施工工艺可以大幅度提高钻孔灌注桩单桩承载力。

In the pile construction of high - rise building projects, the bearing capacity of single pile directly has an impact on the eeonomie and teehnieal indicators of pile eonstruetion. The post grouting technique of east - in - place bored pile can greatly improve the bearing capacity of bored pile.
