不同长径比对旋挖灌注桩桩身侧摩阻力的影响分析

Analysis of influence of different length-diameter ratio on side friction resistance of bored pile

在分析桩身侧摩阻力影响因素的基础上,对桩身周围土体性质、桩身与桩周围土体界面条件及桩端进入持力层的深度等因素进行限定,通过改变桩身长径比,来分析研究桩身侧摩阻力的发挥情况。

Based on the analysis of the factors affecting the side friction resistance of the pile, the properties of the soil around the pile, the interface conditions between the pile and the soil and the depth of the pile tip into the bearing stratum are limited, and the exertion of side friction of pile is analyzed by changing the ratio of length to diameter of pile shaft.
