摘要
通过分析顶管工程施工时对周围土体扰动的作用机理,运用MIDASGTS/NX对顶管施工过程中对地铁高架基础的位移、内力的影响进行数值模拟,针对该法在施工中对周围土体扰动及已有铁路轨道的影响进行了研究。评估了顶管施工对地铁高架基础的影响程度,验证了项目中顶管法施工方案的可行性。
By analyzing the mechanism of the disturbance to the surrounding soil during the construction of the pipe jacking, the MIDAS GTS/NX was used to simulate the pipe jacking construction to explore the influence of displacement and internal force of this method on the subway viaduct foundation and the surrounding soil. The influence of this method on disturbed soil and existing railway track during construction have been studied. The degree of influence of pipe jacking construction on the viaduct foundation of the subway was evaluated, and the feasibility of the pipe jacking construction scheme in the project was verified.
