摘要
本文在阐明唐山市区的地质、水文地质条件的基础上,讨论了市区岩溶塌陷的分布特征及其控制因素,并探讨了地面变形的形成机制,提出了防治措施.
New Tangshan is suffering from the damage of land deformation, which is caused by karst collapse. This article is aimed at the character of land deformation in New Tangshan. In the article, the author gives out the topographical and geomorphologic characters, the geological structure and the conditions of hydrogeology in New Tangshan. The characters and distribution of land deformation in New Tangshan have been pointed out also. The author belives that: (1) the land deformation is related to geological structure and the development of karst; (2) the land deformation is limited by the thickness of sediment, the kind of rock and it's structure. (3) the land deformation is distributed mainly to the region of depression cone. The methods of preventing land deformation in New Tangshan are pointed out in this article.
