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。

Based on the systematic analysis of available data, including the changes of surface drainage system and their relationship with the development of Nandong underground river system, some new conclusions have been reached:(1) The present Nandong underground river system is evoluted from several independent surface and underground rivers; (2) The orie.
本文从地貌学的角度,着重研究了云南南洞地下河流域地貌特征和地表水系的变迁及其与地下河发育的关系,并在此基础上提出了南洞地下河具有继承地表河(干谷、盲谷)发育的新的认识。
补充资料：双牌坊溶洞群
位于县境双堡乡，距县城40公里，距成都市130公里，与内江、资阳、自贡等市相邻。景区总面积2平方公里，分为双石牌坊、溶洞、中华水库三个旅游点。 贞节坊既是研究儒家礼学的重要史料，又是建筑雕刻艺术的宝贵遗产。据仁寿县志载，县境内各类贞节坊、列女坊、节孝坊、功德坊遍及乡里，建国后由于各种原因皆遭破坏，中华乡石坊为仁寿县仅存之物，是一座不可多得的艺术宝库，行人至此，无不为其精美的雕刻赞叹不已。
