钻孔后压浆灌注桩承载力试验研究

Stress Measurement for Jet Grouting Bored Cast-in-situ Pile and Analysis of Pile-soil Load Transfer Behavior

介绍了钻孔后压浆灌注桩施工工艺和加固机理，并根据原位测试结果分析了钻孔后压浆灌注桩荷载传递规律和大面积堆载试验对承载力的影响。

The paper introduces the construction technique and mechanism of increase of bearing capacity for jet grouting bored cast-in-situ piles. According to field testing results, both the pile-soil load transfer behavior and the effects of high-tunage piling-up testing were discussed.
