横观各向同性多层地基中单桩的弹性沉降分析

Elastic settlement of single pile embedded in the layered transversely isotropic medium

运用弹性理论法,分析了横观各向同性成层地基中的受轴向荷载的单桩沉降特性,重点分析了持力层深度、软弱下卧层性质对桩基沉降的影响.通过与工程实例计算结果比较,表明本研究结果具有较高的计算精度,为实际工程中预估单桩和群桩的强度和沉降以及桩基的承载能力提供了一种比较准确的方法.

Based on the elastic theory, the settling characteristics of the axial single pile embedded in the layered transversely isotropie medium are derived. With the aid of a large number of engineering cases, a comparison is made with the theory parameters to illustrate method. The main purpose of this article is to deduce the effectiveness, accurateness and reliability of this the accurate and reliable engineering estimates for the single pile and pile group settlement as well as the strength and bearing capacity of pile embedded in the layered transversely isotrepic soil. Also a powerful tool for analysis of the settlement of single pile and pile group in the layered soil is provided.
