摘要
软土在我国分布广泛,常见于沿海和平原地区,以海相沉积和湖相沉积为主,同时河漫滩沉积相和沼泽沉积也较为多见。工程建设中通常在淤泥或淤泥质土区域发现软土,公认是一种十分不利的土层结构。本文从国内主要软土分布区域入手,归纳总结近年来沿海、平原和山区三类不同沉积环境下软土研究进展,并重点关注软土微观尺度研究成果,最后重点关注工程建设领域,归纳总结目前常用软土处理方式,以期对后续软土宏观分布、微观结构研究,以及工程处理方式提供一定参考。
Soft soil is widely distributed in China,commonly found in coastal and plain areas,mainly composed of marine and lacustrine sediments.At the same time,river floodplain and swamp sediments are also more common.In engineering construction,soft soil is usually found in areas with silt or muddy soil,which is widely recognized as a very unfavorable soil layer structure.This article starts with the main distribution areas of soft soil in China,summarizes the research progress of soft soil in three different sedimentary environments,namely coastal,plain,and mountainous areas,and focuses on the microscale research results of soft soil.Finally,it focuses on the field of engineering construction and summarizes the commonly used soft soil treatment methods,in order to provide some reference for subsequent research on the macroscopic distribution,microstructure,and engineering treatment methods of soft soil.
