PHC管桩在老黏土地区的水平向承载力性状的数值分析

基于PHC管桩在老黏土地区作为竖直承载桩的成熟应用,考虑到PHC管桩对工程地质条件适应性强、施工速度快、现场无污染等诸多特性,通过运用FLAC3D有限差分分析软件对PHC管桩在老黏土地区水平承载力的数值分析,研究了水平荷载对桩身水平位移、水平应力、弯矩的影响,分析了土体的塑性变形,得出了PHC管桩在老黏土地区的水平向承载力性状规律,为PHC管桩在老黏土地区作为水平支护桩的推广应用提供了科学的理论指导。

Numerical Analysis of Horizontal Bearing Capacity of PHC Pipe Piles in Paleo-clay Area

Based on PHC pipe pile in paleo-clay as a mature application of vertical bearing pile,considering the PHC pipe pile in engineering geological conditions of strong adaptability,fast construction speed,no pollution in construction plant and many other features were studied by using FLAC3Dfinite difference analysis software.The PHC pipe pile horizontal bearing capacity numerical analysis in paleo-clay area,the horizontal load on the horizontal displacement of pile,and the horizontal stress were also analyzed.The influence of the bending moment and the plastic deformation of soil were explored,the level of the PHC pipe pile in paleo-clay area of the bearing capacity characters was summarized.The results were providing scientific theoretical guidance for PHC pipe pile application in paleoclay area as laterally soldiers pile.
