Abstract

Now in the territory of Ufa deformation of buildings, emergence of failures and landslides, various by the sizes, is observed. However, despite manifestations of dangerous geological processes, the city is built up. The main building of the territory happens on Ufa Belsky a watershed. These are rather small territories over the surrounding plain more than on 100 m. On this square the city is placed, but now there is “consolidation” of the urban area and not only the topmost surface of a watershed, but also slopes of river valleys, ravines and beams is built up. The city is built on the Perm breeds of the Kungur and Ufa tiers. The Kungur deposits are presented by plasters with power more than 200 m, and rainfall of the Ufa tier blocking them is executed by terrigenous education with power up to 60 m. The territory has a block structure, and is broken by the system of breaks. In plates of plaster ancient karst processes proceeded. There were buried funnels and cavities. The blocking plaster breeds of the Ufa tier of a vodopronitsayema. It should be noted that at development of the city not only surface and soil, but also technogenic waters go to the spreading layers. Loading from the built buildings increases cracks in plaster layers, and water contributes to the development of karst processes. Finally new funnels are formed, there are failures. On a watershed there are cracks of side withdrawal, it leads to formation of landslides and collapses. Breeds of the Ufa tier create soluble minerals. The waters coming to plaster layers dissolve and wash away them. There is a process of a denudation,
