后注浆法钻孔灌注桩在建筑桩基施工中的应用

摘要

This paper respectively carries out post-grouting bored pile construction treatment and bored pile construction treatment, testifies finished pile quality with static load test, and points out advantages of post-grouting technology, such as improving pile end bearing layer and pile surroundings, enhancing comprehensive bearing capacity of pile foundation, as well as reducing subsidence of the foundation.%针对某工程场地分别进行了后注浆钻孔灌注桩施工处理和钻孔灌注桩施工处理，并通过静载荷试验对成桩质量进行验证，指出后注浆施工工艺，可明显改善桩端持力层及桩周条件，在提高桩基综合承载力的同时也有效地减少了地基的沉降量。
