砂土的變形特性

內容概要

揭示土體的本質一直是土力學領域發(fā)展的重要課題。本書是作者通過多年工作實踐在砂土變形特性方面研究的簡略總結。內容包括四部分：第一部分(第一、二章)對砂土的狀態(tài)相關剪脹特性作了比較詳細的概述；第二部分(第三、四、五章)分別介紹了砂土的小應變特性、三軸空間砂土的變形特性以及復雜荷載作用下砂土的變形特性；第三部分(第六章)介紹了砂土的狀態(tài)相關剪脹理論以及統(tǒng)一的砂土本構模型；第四部分(第七章)介紹了緊密砂土中剪切帶的形成過程及其數值模擬。    本書可供有關科研、設計和工程單位的科技工作者參考，也可作為高等院校土木、水利、工民建等專業(yè)研究生的教學參考書。
