Study On Design And Calculation Method Of Embedded Anti Slide Pile

Landslide is a natural disaster in mountainous areas.When the landslide occurs,the landslide is accompanied by huge movement energy and destructive power,which not only cause damage to the local environment,but also seriously endanger people's lives and property safety.Especially in recent years,China's accelerated urban and rural construction,a lot of infrastructure projects have been affected by the landslide hazards.In the mountainous area of Southwest China,there are many development and easy to slip strata.When the external factors are affected,the area is very likely to be relatively large scale,serious harm to all kinds of landslides.Therefore,we should pay enough attention to the prediction and prevention of landslide in this area.As the landslide is the most common application of the treatment engineering of a retaining measures,anti slide pile is by itself and surrounding the anchorage zone of rock and soil are embedded and tight,the cantilever subjected to the landslide thrust transfer to the anchoring section of stable formations,is anti slide pile is the stable formation of its anchoring effect and passive resistance to assume sliding body acting on anti slide pile cantilever sliding body residual sliding force,to achieve the stabilization of landslide to engineering structures.But at present,sunken anti slide pile design level is still in a low level,which the most important reason is the current theoretical research did not fully understand the sunken anti slide pile and soil interaction.In this paper,the interaction between the embedded anti slide pile and the landslide mass and the design method of the embedded anti slide pile are discussed and studied.1.The calculation model of the embedded anti slide pile is established,and the calculation method of the length of the cantilever section of the embedded anti slide pile under different conditions is derived.2.The finite element analysis model of embedded anti slide pile is established,and the influence of the design parameters on the anti slide pile is obtained.3.Based on the analysis of the working process of the embedded anti slide pile and the landslide,the calculation formula of the maximum pile spacing and the calculating formula of the minimum pile spacing are derived.Get the pile spacing can meet the safety requirements,namely according to the calculated pile spacing to embedded type anti slide pile layout,embedded anti slide pile can meet the requirements of landslide control;at the same time,but also to meet the economic requirements,namely according to the calculated pile spacing to decorate the embedded anti slide pile for sunken anti slide pile amount of material in the most reasonable.4.in based on the analysis of previous studies of sunken anti slide pile internal force calculation and the anchorage length was determined for further modification and perfection.5.Combination of Fengdu Luo family courtyard landslide governance of sunken anti slide pile in practical application,and in front of the theory analysis,test in front of the results of theoretical analysis the rationality and reliability of.
