摘要/Abstract

摘要： 通过大量的软土物理力学试验和微观结构分析，结合前人的研究成果，分析了珠江三角洲软土的沉积环境、微观结构、矿物成分，解释了珠江三角洲超软土的形成和工程特性差的渊源.总结了三角洲洲内不同地区软土的分布规律和物理力学性质指标特征，对比分析了珠江三角洲地区软土与国内其他沿海地区软土工程特性的主要差异，可为本地区工程建设提供一定理论依据和参考.

关键词: 珠江三角洲；软土；物理力学性质；对比分析

Abstract: Based on the results of a large number of physical and mechanical tests, microstructure analysis and previous studies, the sedimentary environment, microstructure classification, mineral composition of soft soils are analyzed, and the geologic origin of super-soft soil and the reasons for poor engineering properties are explained. Moreover, the distribution and main physico-mechanical properties of soft soil in various regions of the Pearl River Delta are analyzed, and the engineering properties of soft soils in the Pearl River Delta are compared with that in other coastal areas in China. Thus, the research can serve as good reference for construction projects in the Pearl River Delta area．
