Passive Pile Calculation Model and its Reasonable Distance of Piles
The traditional method of calculating soil arch effect was described Firstly, and the inadequacy of traditional methods was analyzed. On the basis of their predecessors, the rectangular cross section of a rational spacing between passive pile was mainly discussed. Based on the mechanical properties of soil between anti-slide piles analysis, a pile of soil conditions of static equilibrium, cross-section strength of the section of the conditions and strength condition of the arch to common control methods to determine the critical pile space were put forward.Relatively reasonable a spacing formula for calculating pile spacing has been obtained. Comparing with rational pile space formula obtained and the traditional formula for the actual project data, the results indicate that, for the cross-section 2.5mx2.5m the pile, formula by rational pile space the calculated results and the calculation method has been compared and analyzed the results, when the landslide thrust 47kN/m2.According to rational pile space formula the results calculated by the situation more in line with the actual project, it is of significance to practical engineering design of anti-slide pile, and there is a greater using and reference value for the similar project via the methods used and the conclusion.
