桩-网复合地基工后沉降和桩土应力比的计算

本研究简述了土拱理论和薄板变形理论。在桩-网复合地基中,基于土拱理论、薄板变形理论和Winkler弹性地基模型,提出了桩-网复合地基工后沉降计算方法和桩土应力比计算方法,由于该计算模型考虑了桩-网复合地基各组成部分之间的相互作用,能够更准确地反映出桩-网复合地基的工作机理,同时克服了传统算法中"2者不能同时未知"的缺陷,并通过工程算例验证了本研究方法的正确性,对于实际工程的应用提供一定的理论依据。

Calculation of residual settlement and pile-soil stress ratio of pile-net composite foundation

Based on the soil arch theory,Deformation plate theory and winkler model,a method was proposed for calculating residual settlement and pile-soil stress ratio of pile-net composite foundation.As such method takes into account the interaction of the various components of the pile-net composite foundation,the theoretical model showed the working mechanism of the pile-net composite foundation more accurately and overcame the shortcomings of traditional methods.More importantly,the model was verified by an engineering example and hence provided the basis for practical engineering.
