摘要
采用后注浆技术不仅可以大幅度提高基桩的承载能力、减少桩顶沉降量,同时基桩的承载性状也会得到改善。通过试桩的Q—s曲线,并将试验结果与理论计算结果进行了比较。研究结果证明,后压浆技术可以有效地提高基桩的承载力,并能明显减小桩的沉降。
The post-grouting technology could improve the bearing capacity of bored cast-in-place piles, and the reinforcing mechanism of the post-grouting technology differs in different soil strata, the 0 s curves are got and the test results are compared with the calculating ones. The resuits show that the technique of post grouting can effectively improve the piles bearing capacity and significantly reduce the pile settlement.
