Mengzi Dongshan Karst Piping And Structure Research

The development of karst pipeline distribution in large part by the factors such as strata,structure,terrain and physiognomy conditions of comprehensive control and influence.The structure is karst pipe main controlling factors of the development and evolution.The development of karst pipeline distribution in large part by the factors such as strata,structure,terrain and physiognomy conditions of comprehensive control and influence.The structure is karst pipe main controlling factors of the development and evolution.Carbonate rock karst area of joint and fissure karst water infiltration is priority access,is also the leader of the karst development.Fold and fracture often controls the internal structure of karst groundwater flow system and the flow direction,karst cave,karst springs for karst underground space development and distribution of karst water provide instructions,which finally impact on the development of underground river.And the development and evolution of the karst conduit is a long—term continuous process,by 14 c dating,since 46000,mengzi dongshan district karst caves in general continued evolution,and is affected by the new tectonic movement,in vertical and horizontal movement is strong,and multiple phase and stage,further promoted the development of karst conduit.Macro structures are often composed of micro structure development,the development of karst conduit can be traced back to the mineral rock pyrolysis.This article obtains from the research area of carbonate chip,analyzing the characteristic of the karst fissure,joint form inside the rock,summing up the extension direction of small concealed fault,and the karst big spring,cave is influenced by structure on the morphology of comb,in the process of exploring the whole structure of function and performance of the development of karst conduit close combination with regional geological structure,and combined with the space—time characteristics of the development of karst conduit of typical karst pipe model is set up,finally divided into karst distribution pipeline system.
