摘要
新疆某无压输水隧洞饱和水土体洞段在未完工的情况下被水长时间浸泡,造成围岩二次加速变形,通过浸水前后收敛变形数据反演土体物理力学参数,并对隧洞衬砌结构内力及配筋结果进行对比验算。
The uncompleted and saturated section of one pressure-free water transmission tunnel in Xinjiang is immersed in a long term. This causes a secondary expediting deformation of the surrounding rock. Through the data of convergence and deformation of the surround- ing rock before and after being immersed, the physical-mechanics parameters of the soil mass are derived in inversion. Meanwhile, the internal forces and reinforcement arrangement of the tunnel lining are compared and verified.
