在横向受载桩的设计中,必需考虑桩顶位移和桩内最大弯矩。文章提出了一种新的用于计算单桩横向受载的半解析方法。它以简化的p-y土壤响应理论为依据,描述了用于粘土中单桩这种解析方法,将这种方法的预报结果与m法、有限差分法的计算结果进行了比较,发现弯矩分布符合得很好。

During the design of a laterally loaded pile,it is essential to study the deflection of the pile top and the maximum bending moment in the pile.A new semi-analytical method has been proposed in the paper for the calculation of the lateral loads on a single pile,which is based on the simplified p-y soil response theory.The paper gives a description of the algorithm for single piles in clayey soils and compares the predictions achieved by using this algorithm with the calculated results by the m method and the finite difference method.The comparison shows that the distribution of bending moment agrees very well.
