摘要:

以广州地铁四号线仑—大区间盾构施工为依托,通过三维有限元模型预测盾构向前推进时舱体设定土压力引起的地表变形值,对盾构施工变形问题进行研究。同时结合现场监测结果的对比分析,总结了地表沉降规律,对后续工程施工具有指导意义。

Abstract:

 Taking LuntouDaxuecheng section of line 4 of Guangzhou Metro as example, the author predicts the value of the surface deformation caused by the soil pressure in the excavation chamber shield tunneling by means of 3dimension finite element models. The author makes a profound study on the deformation problems in shieldtunneling. On basis of analysis and comparison of the site measurement results,the author summarizes the surface subsidence patterns. The paper can provide guiding significance for the construction in the future.
