| 摘 要： | 基于实际工程中出现的MJS水平旋喷桩施工过程中出现的地表沉降过大的现象，运用FLAC3D软件，分析水平旋喷桩在不同注浆置换率条件下加固地层所产生的地表沉降值，探求在水平旋喷桩施工过程中地表的沉降规律。同时，计算了不同注浆置换率条件下盾构开挖过程中的地表沉降，总结出不同置换率条件下地表沉降变化规律。

Analysis of Ground Settlement during Construction of MJS Horizontal Jet Grouting Piles |
| |
| Abstract: | In relation to the excessive subsidence of ground surface occurring in the construction of MJS horizontal jet grouting piles in actual works, the value of ground settlement caused by strata consolidation for the piles under different rate of grouting replacement was analyzed with FLAC3D software. The law of ground settlement in the construction of horizontal jet grouting piles was searched for. Simultaneously, the value of ground settlement during shield excavation under different rate of grouting replacement was calculated to summarize the change law of ground settlement under different rate of grouting replacement. |
