遵义金塘谷地岩溶塌陷形成机理初步探讨

A Preliminary Discussion on the Formation Mechanism of the Karst Collapses in Jintang Valley, Zunyi, Guizhou

本文通过对遵义金塘谷地岩溶塌陷特征及塌陷区工程勘察资料的综合分析,在阐述了致塌的内外因素及形成条件后,着重探讨了浮托力、自重力、卸荷张力、冲刷力及冲击力在塌陷中所起的作用,并以此提出了防治措施。

Through comprehensive analyses of the features of the karst collapses in Jintang Valley, Zunyi, and the engineering prospecting data of the collapse area, this paper deals with the inner and outer factors and forming conditions of the collapses and the actions of buoyant and supporting force, self-gravity, unloading tension, scouring force and blasting force in the collapses. The paper has put forward some proventing and tackling measures.
