摘　　要：灌注桩后注浆工法具有操作简单、可靠性好、费用低、承载力增幅大等优点。为研究该工法对灌注桩承载力的提高效果,对某输变电工程施工的普通灌注桩和进行了后注浆工法的灌注桩进行抗压、抗拔和水平静载荷试验,对比分析了后注浆工法对该土质条件下桩侧和桩端承载力的增强程度,得到了相关试验结果,为输变电工程后注浆灌注桩基础应用提供依据。Technology method of cast-in-place pile post grouting has some advantages such as easy operation, good reliability, low cost and large hearing capacity growth. In order to study and demonstrate the bearing capacity level under the construction of Wangzhuang 220kV power transmission and transformation, a series of tests including both the vertical static loading test and the horizontal static loading test were carried out at site. Some testing results are obtained from the tests, which could be used as a reference in field application.
