Harness Engineering Study On Yupingba Landslide In The Shimenkan Hydropower Station Reservoir Area

Based on the control engineering of Yupingba landslide at Daozhen county in Guizhou province, the stability, engineering design, construction scheme and engineering management scheme are studied in this paper. It provides some experimental and theoretical basis for further studying in this field. Main points are shown as follows:l)The areal geology, hydrogeology, engineering geology and mans activity are investigated about reservoir area of Shimenkan power station in the drainage area of the Furong River. The disaster of landslide is evaluated.2)Through examination and site investigation, and combine pioneering data, the origin is systematically analysized. The paper put forward that the own factor of rock about litthology and geological structure are intrinsic factor, natural conditions and mans activity are extrinsic factor.3)The development process is studied; the stability of landslide is analyzed by transfer coefficient method. Moreover, the paper evaluates the effection of raising of water level and flow pressure and earthqure to the the stability of landslide.4)Through analyzing different schemes, landslide control are provided. They are anti-slide pile, rubble pitching, drain measure and afforest measure.5)The feasible measure in construction scheme, water and soil conservation and environment protection are put forward, and the manager project after harnessing is suggested.
