摘　　要：以某地铁下穿运营线路工程为依托,使用ANSYS软件建立有限元模型,计算得出岩体的应力场演化规律;布设监测点位,对岩体的破坏程度进行监测。结果表明:对计及应力场演化规律进行监测,不同岩体的应力场演化规律监测结果与实际情况基本一致,差异化岩体状态分析内容符合实际情况,可在实际工程中进行推广应用。Based on the project of a subway undercrossing an operating line,a finite element analysis model is established using ANSYS software.The stress field evolution law of the rock mass is obtained through a series of calculations.Monitoring points are set up to monitor the degree of damage to the rock mass.The results show that the evolution law of the stress field is tested.The monitoring results of stress field evolution of different rock mass are basically consistent with the actual results,and the content of different rock mass state analysis is consistent with the actual situation.It can be promoted and applied in practical life.
