摘要
软土地基区域因其特殊的地质土层特性,导致外部施工对轨道交通结构的影响有较大差异。如何根据地质勘察参数建立有限元模型,分析外部施工对轨道交通结构的安全影响程度,并建立安全监测机制指导现场施工作业,是分析研究的重点。
Due to the special geological soil characteristics in the soft soil foundation area,the impact of external construction on the rail transit structure is quite different. How to establish a finite element model according to the geological survey parameters,analyze the safety impact of external construction on the rail transit structure,and establish a safety monitoring mechanism to guide the construction operation is the focus of this paper.
