【摘要】 结合乌鞘岭隧道7号斜井对复杂地质条件下特长斜井的支护选型进行了分析,并利用Adina有限元计算程序,对开挖支护方案进行了数值模拟,论证了各施工步斜井支护的稳定性,为复杂地质条件下特长斜井支护方案的研究提供了理论依据。更多还原

【Abstract】 This paper combinate the Wushaoling tunnel slope to analysis extra-Long tunnel slope choice of supporting,and imitation calculated the excavation and supporting process by using Adina finite element method.Forecasted safety of structure in the proceduring of excavation,theoretical base and guidance are provided for real engineering and some meaningful results are achieved.更多还原
