Application Research And Design Method Of Reinforced Concrete Anti-slide Pile In Highway Slope Engineering

In the new urbanization construction project,the construction of county-level expressway network keeps rising,and a large number of construction sections need to fill high embankment and dig deep cutting,so the stability problem of the resulting slope is increasingly serious under the condition of long-term sun and rain.At present,anti-slide pile is often used to solve the problems of highway slope.However,the influence of anti-slide pile and its soil arch effect on the slope stability poses a challenge to its application.On the basis of discussing the influence of pile spacing on the performance of anti-slide pile,this paper studies the design of anti-slide pile in slope engineering,analyzes the working mechanism of anti-slide pile,gives the optimization design method of different connection modes,and applies the research results to the treatment of highway slope.Considering the soil arch effect,the calculation process of landslide thrust of anti-slide pile on highway slope based on transfer coefficient method is constructed and verified.At the same time,the design scheme of anti-slide pile spacing is further put forward,the design of double-row anti-slide pile is optimized by using four ways of anti-slide pile connection,and the design scheme is synthetically analyzed and verified with a practical case of highway slope treatment.Finally,the conclusion of practical engineering that can be used in the design of slope anti-slide pile support is drawn,which can be summarized as follows:1)The pile top connection method in front and back row can effectively reduce the bending moment and deformation of the anti-slide pile in back row,and indirectly enhance the actual anti-slide ability of the anti-slide pile to a certain extent.Therefore,it can be used as a reference method to guide the actual slope control engineering.2)Under the four connection modes,the actual stress and deformation of the anti-slide pile will be affected by the pile row spacing,and the influence on each is basically the same,and the trend of change is consistent with the depth of the pile.3)The control variable method is adopted for the anti-slide pile to ensure that other conditions remain unchanged.Matlab software is used to calculate the different pile row spacing between the front pile and the back pile respectively.It is found that the maximum displacement of the front and rear pile top connection and the total piletop connection is smaller than that of the same row pile top connection and the non-pile top connection.Figure [33] table [7] reference [53]...
