The Formation Mechanism And Management Plan Of The Landslide Based On Deformation Monitoring

Based on the condition of deformation monitoring of landslide^[4]governance design is aimed at engineering on-site landslide deformation monitoring with a simultaneous exploration,based on the results of deformation monitoring and the exploration of landslide dynamic governance design,with strong design targeted,governance short design cycle,low economic cost,etc.In landslide treatment engineering can and coordinate the construction of the proposed construction project,can achieve the goal of guarantee landslide exploration design and management,can decrease again and the influence on the construction progress of the proposed construction project,is a kind of efficient and economic design measures for landslide.But due to the division of their respective different exploration,design and construction units,the responsibility division is relatively clear,survey design and construction of landslide governance is assembly line work,there is no obvious between exploration,design and construction units operation time lap,not only cause delay engineering landslide is the optimal timing of governance,and proposed project construction schedule delay.Therefore,it is of great importance to carry out research on the theory of engineering landslide exploration design based on deformation monitoring conditions,which has important scientific theoretical significance and engineering application value.Based on the Ya li ping post-disaster reconstruction in the area north of landslide treatment engineering design as the research object,this paper meteorological hydrology,topography,stratum lithology,geological structure and hydrogeological condition,on the basis of combining the artificial different parts of landslide deformation monitoring data,using data from simulation results,grasp the development trend of artificial landslide deformation,timely and accurate design design of landslide treatment,artificial landslide provides important basic data for scientific governance.The following main results are obtained through the research:?1?According to the field engineering geological mapping and exploration engineering,the north side of the landslide in the Northern Slope of the cliff area is a medium-sized loess landslide,and the landslide number is H1.Due to the construction of the community,the construction of the old landslide slope is artificially excavated,resulting in the rise of the old landslide,and directly threaten the safety of the construction workers and equipment in the residential buildings of the 50#-53#residential building.?2?The deformation monitoring of different parts of the landslide was obtained through the whole station,and the deformation of the trailing edge and slope of the landslide was obtained.The depth of sliding surface is determined by drilling and well probing into the strata lithology and groundwater depth.?3?Using the Midas numerical simulation of the deformation monitoring data,the exploration of stability calculation results with Midas fitting data simulation,determine the development trend of artificial landslide deformation and landslide treatment measures are put forward,and in a timely manner to guide the construction unit to carry on the presser foot landslide emergency control measures.?4?Combined with the on-site monitoring and exploration results,the design of artificial landslide control was designed by using relatively mature paring and anti-slide piles.
