A Study On The Slope Stability Of Linyu Villa In Guangzhou

The topics make a large and sufficient advance preparations, Understand andmaster the Regional geological environment of Linyu villa,During the preliminarygeological survey, the author collected a large data of joints in the quarry stone pit.Study of the spatial distribution law for joints measured with Equator-Polarprojection and the principle of probability statistics;and analysis the slope stabilitywith Spush method,Combine with analysis of slope stability based on theMorh—Coulomb principle and software of Fast Lagrangian Analysis , Study on thechange of total displacement under reinforced and unreinforced.then validate thestability of the slope.The paper can be divided into four sections.The fist section introduces the Project planning Profile Meteorological andHydrological study area, topography and the existing gravity deformationphenomenon, with lava rock formations, hydrogeological conditions, and geologicalformations and regional crustal stability.The two section introduces the the analysis of the main factors affecting slopestability ,and determine three damage model. First is landslides and falling stones,second is slide, Third is seeded dirt, and separately for elaboration. Against theslope stability analysis of the damage patterns given slope stability assessment andthe standard method, and introduce the stability calculations.as the slope is made ofsoil and rock,then we must analysis it with rock theory and soil theory separatly. weanalysis the rock layer with Equator-Polar projection and the principle ofprobability statistics, and analysis the soil layer with Spush method. the result is thatthe rock layer is stability and the soil layer is instability.according the result weneed to inforcement the slope.The third section is designed according to the principles of safety, economy,entireness and preventment in slope treatment. 1. According to the traits of thisproject, we bring forward some basic principles for slope designment , which makecertain the way of preventment and principal project measures . 2. This article alsocarry on the design of anchor bar and briefly introduce the basic anchorage principleand loaded characteristics , with which we carry through anchor cable design .Thetechnique of prestressed anchorage is applied widely in slope reinforcement becauseof its safety ,its simpleness and flexibility ,its right structure , economic cost andshort time limit.The structure of slope-anchor bar don't occupy additional room ,andthe body of slope is pressed once prestress is maked ,so slope's displacement anddeformation are controlled welly , mechanical characters are improved andstabilization is strengthened. 3. We check slope's stabilization by lizheng ,provingthat this inforcement is reasonable and effective with safe factor of 1.51The fourth section introduces that in order to further study the whole stabilityof Linyu villa and the stability of the slope under reinforced,we analysis the slopewith FLAC-2D numerical simulate.
