Bucking Analysis of the Pile in Soil Considering the Interaction of Pile-soil
摘要
Abstract
The soil resistance of pile around is one of the important factors which affects the stability of the pile, thus taking into account the interaction of pile-soil is more reasonable to study the bucking of the pile.The horizontal force of soil to pile is obtained by the continuous conditions at the soil-pile and the orthogonality of trigonometric functions.Based on these results, the bending equation and characteristic equation of the pile are established under three dimensional axisymmetrical cases.The influences of the length-radius factor of pile and modulus factor of pile and soil on the axial critical load are investigated.关键词
