摘要
本文以云南省呈贡新区失地为高原湖泊岩溶地貌的代表,简述了其岩溶洞隙的发育特征;并以农民安置住房雨花2地块二期建设项目为工程实例,借助有限差分软件FLAC^(3D)实现了对岩溶洞、土洞地基自身的稳定性及其加固方案的验证。通过数值模拟发现,针对高原湖泊岩溶地基的处理,无论是埋深11m范围内的单个体溶洞,还是埋深范围在8m^15m的群体溶洞,均可以借助注浆处理方法明显的改善和提高岩溶地基的稳定性。
In this paper,the land lost in Chenggong District of Yunnan province is the representative of the karst landform of the plateau lake,the development characteristics of karst cave gap are briefly described.Based on the engineering example,the stability of the karst cave and soil cave itself and the reinforcement scheme are verified by the finite difference software FLAC^3D.Through numerical simulation,it is found that for the treatment of the karst foundation of the plateau lakes,whether the single cave in the depth of 11 m or the cave in the depth of 8m～15m,the grouting treatment can obviously improve the karst foundation stability.
