摘要: 针对深基坑开挖卸荷对临近既有结构的影响,考虑深基坑三维空间效应,采用midasGTS有限元计算软件,建立三维有限元计算模型,对实际基坑工程施工全过程进行了数值分析,研究该基坑开挖对临近结构的影响性,得出临近结构受基坑施工影响的变形特性规律,并按照现行规范进行风险评估。结果表明,临近结构受基坑施工影响的变形处于安全可控范围内,可为类似工程提供参考。

Abstract: Thispaper presents the numerical studies using commercial software MIDASGTS on the deep excavation on the adjacent structures. The rntire deep excavation process was considered in the threedimensional numerical model by considering the spatial effect so that the impact of the excavation on the adjacent building structures. The deformation of the supporting structure and the risk assessment are evaluated in accordance with the current design code. The numerical analysis results indicate that the deformation of the supporting structure are within the acceptable range.


Key words: Deep Excavation, Adjacent Structures, Numerical Analysis, Risk Assessment
