| At present,under the circumstances of China’s economic take-off,the construction of high-scale large-scale highways in the west,which is spreading toward mountainous areas,is also growing faster.However,the rapid development is accompanied by the problem of insufficient stability of various types of slopes.Due to the unstable slopes of large and small,the personal safety and property losses of our citizens have been highly valued by all walks of life.Since there are still many shortcomings in China’s current technology on geological exploration,there are still many omissions in understanding many complicated issues.In the construction of highways in mountainous areas of China,the stability of slopes is insufficient,resulting in more accidents such as deformation and landslides.It mainly has problems such as large deformation and serious damage to the diffusion surface.It has jeopardized the existing projects and delayed the construction period,which in turn led to an increase in the original investment.It can be seen that the slope accident is not conducive to the sustainable development of safe operation.Slope disasters As a world disaster problem of the same level as volcanoes and earthquakes,the research and treatment of this issue has important social value.The research focus of this paper is on Sichuan’s expressways and analyzes its dangerous landslide control projects.The analysis method is based on ANSYS finite element method and Swedish arc method.In the reasoning of its stability,the precautionary anchor cable anchor is used as the framework,and the prevention measures of steel pipe pile and anti-slide pile are supported.In the optimization of the short slabs of highway landslides in Sichuan,this paper adopts various basic measures such as theoretical exploration,practical experiments,simulation figures and engineering subjects.The main contents of this paper include:1.Classification of the causes,characteristics and prediction modes of landslides through basic theoretical exploration;2.Select a typical construction site for practice,collect the mechanical reference data and the changed data of the rock mass in the slope area through the combination of outdoor and indoor practice,and provide practical basis and digital proof for the theory.3.Inferring the deformation law of the slope by analyzing the detected value and taking preventive measures.And improve the stability of parameters in future engineering construction.In the current engineering practice in some areas,the research results of this paper have been effective.In addition to improving the economic and technical benefits of existing construction areas,it also provides reference for other short-slope prevention problems. |
