Abstract
A large number of literatures which had reported soft muddy soil stabilization were reviewed to review the present status and classification of soft muddy soil solidifying materials, summarize and analyze the solidifying mechanism of various solidifying materials in this paper. The results show that the soft muddy soil solidification which has significant economic, environmental and social benefit has wide application potential. Meanwhile, the questions need to be solved at present and suggestions of soft muddy soil solidification have been put forward.
Highlights
The soft muddy soil is considered that unconsolidated soft fine grained soils or very fine soil is deposited and formed in a standing or slow flowing water environment by physical, chemistry and biological effects, which belongs to modern recent sediments
According to natural pore ratio, the soft muddy soil can be divided into the silt and the mucky soil [1]
The solidification treatment technology of soft muddy soil refers to adding solidifying materials for its characteristic to the soft muddy soil to improve its physical and mechanical properties and to meet the engineering requirements
Summary
The soft muddy soil is considered that unconsolidated soft fine grained soils or very fine soil is deposited and formed in a standing or slow flowing water environment by physical, chemistry and biological effects, which belongs to modern recent sediments. According to natural pore ratio, the soft muddy soil can be divided into the silt (natural moisture content is greater than the liquid limit and natural pore ratio is equal to or greater than 1.5) and the mucky soil (natural moisture content is greater than the liquid limit and natural pore ratio is greater than 1.0 but less than 1.5) [1]. It is widely distributed in inland areas along lakes, rivers and southeastern coastal areas in China. It has obvious advantages such as wide range for application, high early strength, adjustable strength and available local materials
