后压浆钻孔灌注桩在太原某项目中的应用探讨

Discussion on application of the post-grouting bored pile in a project in Taiyuan

以太原某桩基工程试桩承载力试验为例,介绍了钻孔灌注桩后压浆主要设计参数,通过对比桩基规范计算得到桩基承载力估算值与试桩静载荷试验成果,得出后压浆工艺对提高桩基的单桩承载能力效果显著的结论。

Taking bearing capacity test of the test pile in a pile foundation in Taiyuan as an example, introduces the main design parameters of the post-grouting bored pile. By comparing the estimated value of pile bearing capacity calculated by code of pile foundation with the static load test results, post-grouting technology has significant efficiency in enhancing single pile bearing capacity.
