摘　　要：采用ABAQUS有限元软件分析了浅埋隧道施工在考虑地下水情况下对地表沉降的影响,并与未考虑流固耦合效应进行比较.结果表明,流固耦合计算的地表沉降作用范围比未考虑流固效应要大的多,该研究为控制地表沉降及围岩变形提供了可靠的施工依据.ABAQUS finite element software was used to analyse the condition of ground settlement,and the results were compared with no coupling condition.The results show that the fluid-solid coupling calculation of the ground surface settlement is larger than that of ignoring fluid-solid condition.The research provides reliable basis to control the ground settlement and surrounding rock deformation.
