| 摘 要： | 目前国内外旋喷桩施工经验较少，尤其是超深旋喷桩在施工中易受到诸如地层物理性质、力学性质、埋深、地下障碍物、施工参数等多种因素的影响。本文就采用高压旋喷法对含承压水砂质粉土和粉砂土加固。时参数的合理确定进行了三种工法的对比研究，并评价了相关工法的加固效果。

| Abstract: | There was less construction experience of rotary jet pile domestic and foreign presently. Particularly for the ultra-deep pile it was easily be affected by multi-factor such as physical properties of the formation, mechanical properties, depth, obstructions on the ground floor, construction parameters and other factors. In this paper three construction methods had been comparative studied which been applied in the process of highpressure rotary jet pile construction with the determination of reinforcement factors, then the reinforcement results for corresponding construction method had been estimated. |
