摘要
基于陈至达提出的大变形问题基础理论 ,指出了以传统小变形理论研究软弱围岩隧道大变形问题存在的弊端。运用非线性数值模拟大变形的手段 ,针对二郎山公路隧道在高地应力条件下软弱围岩的大变形进行了研究 ,进而探讨了大变形破坏的本质问题。
Based on the basic principle of large deformation body put forward by Chen Zhida, it is unreasonable to study large deformation tunnel with small deformation theory. The non linear numerical simulation method of large deformation is applied to analyze Erlanshan highway tunnel with large deformation occurrence. Furthermore, the essence of the large deformation occurrence about weak rockmass tunnel under high initial in situ stresses is discussed.
