盖层—岩溶介质体系宏观系统特性研究及若干问题的探讨

The systematic charactristics of cap soil-Karst bed rock and discussion on several problems about the formation of karst collapse

覆盖型岩溶区工程岩土体可以抽象为盖层—岩溶介质体系 ,盖层和岩溶介质通过盖层底部土体和岩溶洞隙充填物接合起来。该体系具有系统性、复杂性 ,自组织性、开放性以及突变性等特征 ,可以处理为一个复杂自组织开放的力学平衡系统。本文采用宏观系统科学的基本思想 ,从宏观到微观对该体系特征及岩溶塌陷防治的方法论问题进行了探讨 ,并对岩溶塌陷研究中的部分问题进行了讨论。

The strata made up with soil and carbonate rock in covered Karst area can be treated as a system of soil cap\|Karst bed rock,which are connected by the bottom soil of cap and the filling materials in Karst caves and fractures. The system,presenting the characters of system, complexity, opening, self organization and sudden change, can be treated as a complex, opening self\|organized system based on the modern theories of system. Several systemic characters and applications of the system are presented in the prevention and cure of Karst collapse from the macroscopic and systematic point of view. Meanwhile several problems on the formation of Karst collapse are also discussed in the paper.
