A slope can be seen everywhere in our daily life.It is a slope formed on both sides of a highway to ensure the stability of the foundation of the highway.It is mainly composed of seven factors: top,bottom,shoulder,foot,surface,height and Angle of slope.Slope is a kind of landform widely appearing in all kinds of geotechnical engineering.The development of slope has a long history.However,because slope is a very complex and comprehensive geotechnical engineering problem,so until today,there are still many problems to be solved in slope.To ensure the stability,economy and practicality of slope engineering is still a very key problem in today’s human society,because sometimes due to geographical conditions,climate environment or human factors make the slope can not be stable,so people think of can use some piles through the slope and make the slope fixed,this is the anti-slide pile.The use of anti-slide pile can save a lot of time,cost and human and material resources,and can greatly shorten the construction period,in addition,because of its wide range of application,good effect,and the surrounding geological environment caused little impact,so it has become the most important and the most common way to prevent and control landslides and other geological disasters.The stability of slope is the result of the joint action of many factors,including the structural characteristics of slope itself,soil properties,landform,geological structure and anti-slide pile supporting parameters,but because the mechanism of action of each factor and related theoretical analysis are not comprehensive,so it needs to be further discussed.This paper focuses on the study of slope stability after anti-slide pile reinforcement.On the theoretical basis of finite element strength reduction method,Midas/GTS finite element numerical simulation software is used to analyze the soil parameters,slope Angle,pile length,pile diameter,pile spacing,pile position and other influencing factors.The feasibility of slope reinforcement by anti-slide pile is explained from safety factor,plastic deformation,sliding surface,soil displacement and anti-slide pile displacement.According to the conclusion,the cohesive force,internal friction Angle and slope Angle of soil are closely related to the stability of slope.But the elastic modulus and Poisson’s ratio have little effect on the stability of slope.The pile length,pile spacing and pile position of antisliding pile have great influence on the stability of slope,but the pile diameter has little influence on it.In this paper,according to the actual engineering case,the establishment of slope model,through the orthogonal experiment method to optimize the anti-slide pile supporting parameters,and then compare and analyze the stability of the slope with pile and without pile to prove that the anti-slide pile reinforcement slope is feasible in the actual project.Figure [38] table [19] reference [78]... |
