一种改进的单桩计算弹性理论法

弹性理论法是单桩计算的经典理论方法。然而在单桩计算的弹性理论法中,假定桩周各桩段所受的侧摩阻力为均匀分布,这与实际工程存在较大的差异。该文针对该问题,引入桩侧各桩段的侧摩阻力为线性分布的基本假定,根据桩土界面位移协调条件,推导了相应的单桩理论计算公式,为桩基计算提供理论参考。

A Elastic Theory to Improve Calculation of Single Pile

The elastic theory is the typical theoretical method of calculating the single pile.However,it is assumed that the pile shaft resistance of each pile section surrounding the pile is evenly distributed in the elastic theory of single pile calculation,which is greater different from the practical engineering.Aiming at this issue,the article deduces the relative single pile theoretical calculation formula by introducing the basic assumption of the pile shaft resistance to be linearly distributed at each pile section of pile shaft and based on the condition of pile and soil interface displacement coordination,which provides the theoretical reference for the construction of pile foundation.
