LABORATORY TESTS ON INTRINSIC COMPRESSION BEHAVIOR OF RECONSTITUTED CLAYS

Chinese AbstractEnglish Abstract

Burland于1990年提出重塑土的固有压缩特性,为定量评价天然沉积结构性黏性土的力学性质提供参考依据.通过对四种液限的重塑土进行大量的室内一维固结试验,重塑土样的初始含水率调整扩大为液限的0.7~2.0倍,探讨了初始含水率,液限对重塑土固有压缩特性的影响.结果表明:重塑土压缩曲线不仅与土的液限有关,还受初始含水率的影响;在较低固结压力下,采用Burland引入的孔隙指数不能将不同初始含水率的重塑土压缩曲线归一化,但当固结压力超过约25kPa时…More>>

Research on quantitative evaluation of the compression behavior for reconstituted clays usually provides a reference framework for interpreting the corresponding characteristics of natural sedimentary clays. The intrinsic compression line(ICL) was proposed by Burland in 1990. The void index was introduced for normalizing the com-pression curves of various reconstituted clays having an initial water content of 1.0 -1.5 times (preferably 1. 25 times) the liqui…More>>
