在软粘土中建造浅埋隧洞引起附近地面下沉的预极是摆在设计者面前的主要问题之一。有限元法和离心模型研究目前已被用来研究隧道变形特性。在意义明确的有效应力条件下研究的结果,提出了予报地面下沉的新途径。
The construction of shallow buried tunnels in soft clay that causes the ground to sink near the pre-polarity is one of the main issues facing designers. Finite element method and centrifugal model study have been used to study the tunnel deformation characteristics. The results of the study under a meaningful and effective stress condition suggest a new approach to ground subsidence.
