随着我国建设事业的发展,许多工程不可避免地要建筑在岩溶地层之上,我国可溶性岩层分布广泛,如何勘探岩溶地基,防止发生病害,是许多工程人员十分关注的问题。本文综合探讨了岩溶地层形成、发展的一般规律,以及岩溶地区地貌的一般特征。通过对几个岩溶地基工程的勘查和加固处理,说明用灌浆或旋喷的方法整治岩溶地基是成功的,值得推荐。文中对灌浆和旋喷的工艺过程也作了简要的叙述。
With the development of our country’s construction, many projects inevitably need to be built on the karst strata. The soluble rock formations in our country are widely distributed. How to explore the karst ground and prevent the occurrence of diseases is a problem that many engineers pay close attention to. This article comprehensively discusses the general rules for the formation and development of karst formations, as well as the general features of the karst geomorphology. Through the exploration and reinforcement of several karst ground projects, it is worth recommending that the karst ground improvement by grouting or jetting is successful. The article also gives a brief description of the grouting and spin-spray process.
