考虑桩端土成层性的位移协调法单桩沉降计算

A Calculation Method for Settlement Analysis of the Single Pile Considered with the Stress Dispersion of Pile End Soil

该文基于位移协调法,提出了一种成层地基中考虑桩端土应力扩散效应的单桩沉降计算方法。通过与传统计算方法对比,该计算方法与实测值较吻合,能反映桩顶荷载沉降变化趋势,可以简捷应用到实际工程中。

Pile foundation is a common form of deep foundation , which is widely used in various types of buildings and structures . While the calculation of pile settlement has been studied quite thoroughly , the underlying soil-pile interaction is not yet .Based on displacement coordinating method , a calculation method discussed in this paper is for settlement analysis of the single pile embedded in layered soils , which can be considered in the stress dispersion of pile end soil .Contrasting with the traditional method , the calcu-lating method in this paper is consistent with the measured value;reflect the load on pile top settlement trend .It can be well applied to practical engineering .
