Landslide Stability Analysis And Control Research On Dahuangtian Landslide In Wanliang Highway

Landslide is an ordinary geological disaster in China. The stratagem of "Western China Development" offers a new opportunity to Chongqing's highway construction. It is very important for highway construction and running to put up landslide stability analysis, fathering research and keep the slope stability for a long time.According to engineering practice during the construction of Wangliang highway, the characteristic of ordinary deposit layer and terrane landslide in project construction is very detaily analyzed in the paper. It is very detaily described on deposit layer landslide's region characteristic, aged landslide body's characteristic and the developing deposit layer landslide's characteristic. The deposit layer landslide's formation, style, and configuration character are also analyzed. The style, configuration character, sigh and development of terrane landslide are very detaily analyzed.The main factor and the judgement method of landslide stabilty are analyzed in the paper. The use condition and calculation process of landslide stability theory on circular arc slide plane, single plane slide plane, fold slide plane and Bishop slice method are expounded in the paper. The calculation evaluation of landslide stability and the calculation of landslide thrust are also descibed in detail.The characteristic of deposit layer and terrane landslide is described from theory to practice. As far as Dahuangtian landslide in Wangliang highway in Chongqing, from the engineering geologic condition to construction factor, the main factor and the stability of landslide are analyzed in detail. The engineering control measure on Dahuangtian landslide are explained in detail according to construction practice.
