| 摘 要： | 该文讨论高压旋喷桩在基坑较深、坑内地下水丰富且水力坡降大的情况下 ,旋喷作业所产生的高压水气激振引起土体液化 ,与地下水渗透压力引起的液化耦合 ,因渗流带走土及水泥中的细颗粒 ,结果影响到旋喷桩的施工效果。

| Abstract: | The paper discussed jet grouting pile to be used as soil foundation improvement under condition of high hydraulic gradient with rich underground water. The vibrating by high pressure gas liquid of jet grouting machine arose liquefaction of the soil body. The liquefaction combines with seepage flow,carries away fine articles, so that both of liquefactions effect on the results of soil foundation improvement. |
