Study On Optimization Of Management Design Of Loess Landslide

Landslide is a geological hazard caused by natural or artificial slope caused by external factors causing the loss of its stability.China is one of the countries with frequent landslides.Different geological conditions and multiple factors have made it difficult to accurately predict landslides,which has led to high landslide control costs.We must do a good job in the prevention and control of landslides.Landslide control will not only affect the duration of the project,but also the cost of the project.At the same time,it will also bring huge risks to property and life safety.Therefore,the optimization of the landslide program not only has important social value,but also meets the requirements of innovative,economical,and environment-friendly engineering in the new era.Based on the consolidated quick shear tests and direct shear(quick shear),saturated residual shear test,etc,on the basis of laboratory experiments,combined with local actual situation,a series of important parameters of rock mass,landslide is defined as the cohesive force,internal friction Angle.The stability of the landslide was verified by transfer coefficient method and midas-gts NX finite element software.Combination with the engineering reality,comprehensive consideration of landslide area of the hydrogeological condition,engineering geological conditions,and the rainfall and the prevention and control of structural robustness influence factors,to carry out the stability analysis and calculation,design of reinforcement measures,as well as to design the governance approach is used for comparison and optimization,and a series of work.Based on the economical,environmental,and innovative requirements of the new era of engineering,this paper starts with different cut slope rates and proposes three other programs for slope cuts on different slope lines to compare the effect of comprehensive treatment and the amount of work.It is mainly to compare the size of the cut-off volume and choose the optimal cut slope rate,which makes the engineering design more economical and environmentally friendly.It was finally determined that the use of cut slopes(a slope of 1:0.6),drainage,retaining walls,and slope greening were the design options.The three-dimensional simulation of the optimal program was carried out using the Midas-GTS NX finite element software to further confirm its effectiveness.
