摘要
以太原漫滩地区某地铁车站施工为例,研究深基坑支护方案的合理性。采用理论分析与有限元相结合的方法,考虑基坑开挖的实际步骤,采用FLAC^(3D)对深基坑开挖的全过程进行数值模拟,分析了深基坑地下连续墙的变形和对周围地表的沉降,得出深基坑采用地下连续墙与内支撑支护形式下基坑变形形式及对周围地表沉降变形特征,从而验证基坑支护设计方案,对太原地铁车站基坑开挖后续设计及施工方案的优化和改进及变形预测都具有重要的参考意义。
Taking a subway station construction in Taiyuan floodplain area as an example, the authors study the rationality of supporting scheme of deep foundation excavation. By using the method of theoretical analysis and finite element method, the deformation of deep foundation excavation and the deformation characteristics of surrounding ground are analyzed. The deformation and deformation characteristics of foundation excavation are analyzed. The design scheme is verified and proved to be important for the design of Taiyuan metro station.
