摘要
本文以上海某盾构法隧道开挖为例,根据原状土卸载应力路径下的回弹试验结果,探讨了土体在卸荷状态下的变形特性,并对盾构法隧道开挖卸荷影响深度进行了初步分析探讨。
Taking the excavation of a shield tunnel in Shanghai as a example,based on the rebound test results of undisturbed soil in the unloading stress path,this paper discussed the deformation of soil under unloading,and analyzed the influence depth of unloading during shield tunnel excavation.
