1) cave foundation
溶洞地基
1.
Currently,the stability evaluation of cave foundation is mostly focus on the quantitative evaluation,such as the collapse mechanism and prevention,while the qualitative assessment is rare.
目前,对溶洞地基稳定性评价研究多集中在塌陷发育机理及预防等定性评价方面,少见定量评价。
2) Soil(karst)cave
土(溶)洞地基
3) solution cavity in terrain
地表溶洞
4) Karst cave area
溶洞地段
5) underground karst cavity
地下溶洞
1.
According to the problem of failure and instability in roadbed and cutting engineering of underground karst cavity,on the basis of inhomogeneous elastic damage model,this thesis propose the FEM back-analysis from instability-strength degradation,to describe inhomogeneity of material suppose that the material parameter obeys statistical distribution.
针对地下溶洞路床路堑工程变形与失稳问题,本文提出了基于非均质弹性损伤模型的有限元失稳-强度折减反分析法,认为材料参数服从统计分布来描述材料的非均匀性。
