摘要
基于某综合管廊下穿既有河道项目,根据现场地质情况利用MIDAS GTS有限元软件建立管廊暗挖下穿既有河道模型,对暗挖管廊对河底沉降的影响进行数值分析,确定管廊暗挖对下穿河道的影响,同时结合实际开挖过程中河底沉降监测数据,对比分析数值模拟河底沉降值的可靠性,为类似工程提供参考依据。
With a project of excavation of pipe gallery under a river,based on geological condition of construction field,the model of pipe gallery under a river is set up by the finite element software MIDAS GTS.When the pipe gallery passes the existed river by excavation,the numerical analysis is made for the influence of excavation of pipe gallery to the settlement of river bottom,to determine the influence of excavation of pipe gallery to the river bottom,and combined with the monitoring data of the settlement of river bottom in the actual excavation process,comparison and analysis is made on the reliability of numerical simulation of settlement value of river bottom,which provides a reference for numerical simulation analysis of similar projects.
