Stability Analysis Of Soil Infront Of Inclined Pile In Self-balancing Composite Retaining Wall

The theory of self-balanced composite retaining wall which is a kind of new blockstructure has some development, but researches for stability of the lower part of theraking piles embedded in soil solid paragraph pile relatively little. As a result, a newtopic has been provided–the analysis for stability of embedded solid sectionOblique pile before the pile of segments embedded soil by the force direction belief,before pile stability and there is more risk relative to the vertical piles.Raking pilesduring working before pile along a sliding surface as a whole slide out and read at homeand abroad on the basis of the information and documentation on the issue this article,and has been studied by previous self-balancing compoundretaining walls theory, acomputational model of the soil in the lower part of the ramp after another, andproposed a calculation method for soil stability analysis of inclined pile.And given todetermine before pile will have to determine the conditions of unstable sliding, usingthe finite element analysis software ABAQUS to simulate the oblique piles and piles ofpre-soil system, the use of the model base of the Mohr-Coulomb yield criteria, theestablishment of closerengineering status of the structural system model on the rampafter another before the soil was calculated and analyzed.The following conclusions canbe obtained through the analysis of pile depth below the mounting surface in accordancewith a certain length is divided into a number of unit segments, each unit segment has acorresponding depth, thus there is a corresponding sliding surface angle values by thecorresponding depthcan calculate the resistance of the sliding surface and sliding forceand angle values thus obtained at different depths in the safety coefficient, the safetyfactor for the most hours of the depth at the sliding surface as the most unsafe slidingsurface, in order to determinethe most unfavorable in which the depth of the slidingsurface.And ABAQUS simulation results of the analysis consistent with the theoreticalconclusions.The research of this subject complements embedded soil stability analysis of thevacancy in the solid segment pile on the soil since the balanced composite retainingwall, oblique pile of top soil stability calculation models and methods, as well asdetermine the conditions, making the self-balancing compound blockwall theory ismore perfect, while according to the research findings to judge the range of unstable soilin front of the pile, and to guide the actual works on unstable soil timely reinforcement processing.
