Finite Element Analysis of New Hydraulic Tunnels Underneath Existing Railway Tunnels
The ABAQUS finite element software is used to establish a three-dimensional finite element model wearing a high-speed railway tunnel structure under the newly-built aquarium tunnel.Through the numerical simulation method,the impact of the stress deformation of the newly-built water tunnel excavation on the existing high-speed railway tunnel is analyzed.The analysis results show that the sedimentation area of the high-speed railway tunnel caused by crossing is mainly distributed in the intersection of the two tunnel spaces.The overall sedimentation of the high-speed railway tunnel is small,and the maximum settlement value is 4.03mm.The maximum tensile value generated by the high-speed railway tunnel lining is about 1.5 times before excavation.
