Study On Soil Arching Effect And Numerical Simulation Of Anti - Slide Pile

In this study,the mechanic of soil arch between anti-slide piles in different groud will be analysed, and based on this, the soil arch effect in defferent groud will be reaearched and the calculation method of critical space beteewn piles will be decided.Based on theory analysis, the mechanic of forming soil arch, parameters of soil and the roughness of interface between soil around piles will be investigated by means of the FEM.The chiefly contents are as follows:1. Theoretical analysis of the size of the main stress arch anti-slide pile between the clay in the soil arching mechanism, further analysis of the type of soil in between the arch anti-slide pile of soil under. Finally, numerical simulation method to analyze the formation mechanism of soil arch between piles and further illustrate the above theoretical analysis.2. In summary arch arching effect according to the basis of soil arching between theoretical research on anti-slide pile soil analyzes cohesive set among anti-slide pile of soil. Conducted soil theory aspects arch arched foot arch beam method effect on the position and shape of the arch, the arch of the destruction of soil conditions, in-depth research, and reasonable conclusions and cohesive slide Pile Based on the above conclusions critical method of determining pile spacing.3. For cohesive soils,soil arching confrontation between slippery pile a lot of numerical simulation,the influence of various factors on the arch between piles. And the numerical simulation of the findings and the previous theoretical analysis compared obtained consistent results, further evidence of the theoretical analysis.
