| 摘 要： | 云南高原岩溶塌陷总的特征是由岩溶高原特定的地质环境、岩溶发育、水文地质以及水文气象和人类工程活动等因素综合影响和决定的，文中通过对这些因素及其作用机制的分析，深化了对高原岩溶塌陷基本特征和发育规律的认识。云南高原岩溶塌陷区域上分布零星，地段上呈现“点状”特征，主要集中发育于岩溶断陷盆地、岩溶槽谷（洼）地、岩溶台地或古高...

| Abstract: | The general characteristics of karst collapse in Yunnan plateau is comprehensively influenced and determined by the specific geological environment, karst development, hydrogeology, hydrometeorology and human engineering activities. This article analyses these factors and its mechanism, deepen the understanding on the basic characteristics and development law of karst collapse. The karst collapse in Yunnan Plateau is sporadically distributed, showing "point" characteristics, and mainly develops in karst geological environment units such as karst faulted basin, karst trough valley (depression) land, karst platform or ancient plateau surface.The main reason is that most of the plateau is exposed bedrock mountainous area, with deep rivers, vertical karst zones and deep groundwater.In basin, valley, depression and other areas inhabited by human beings, the overburden of loose soil is thicker, the proportion of cohesive soil layer is higher, and the degree of soil consolidation is higher, except for the marginal zone.Karst development is not uniform, karst caves and tubes are developed, but the underground karst rate is not high in general, and the caves and tubes that cause karst collapse are isolated and scattered. |
