摘要
综合考虑长江路九号街区基坑工程复杂的周边环境和工程地质条件,对该工程支护体系在施工各阶段的土压力、位移、弯矩和剪力进行计算分析,采用有限元软件FLAC模拟分析基坑开挖对地铁线路的影响。文章指出采用文中方案进行支护能满足工程要求,并且能将基坑开挖对地铁线路的影响降低到可接受范围内。
Taking the complex surrounding environment and engineering geological conditions of the foundation pit project of No.9 block of Changjiang Road into account, this paper calculates and analyzes the soil pressure, the displacement, bending moment and shear force of the supporting system at all stages of construction, and carried out a simulation analysis of the influence of excavation on subway line by the use finite element software FLAC. Results shows that the support scheme in the paper can meet the project requirements and the influence of excavation on subway lines will be controlled within the deformation control requirements.
