| 摘 要： | 通过对钻孔灌注桩注浆加固机理的研究 ,针对持力层为砾石层的桩提出了模拟注浆后桩体特征的变截面桩身模型。采用荷载传递法 ,对现场实测的注浆前后荷载 -沉降曲线进行了计算和拟合 ,并对比分析了注浆前后桩的承载力与变形状况 ,最后分析了注浆后桩P -s曲线的一些特征

| Abstract: | Studying the Stabilization mechanism of grouting at the bottoms of cast-in-situ piles, a model of vary-section pile is given here for the pile bearing at gravel layer. Using load transfer method, the load-settlement curves are calculated before and after grouting, and the bearing capacities and deformation are analyzed for piles whether grouted. Some characteristics of P-s curves are analyzed herein. |

| Keywords: | cast-in-situ pile grouting load-settlemant curve |
