膨胀土边坡失稳与防治研究

Research on Instability and Prevention of Expansive Soil Slope

膨胀土作为一种广泛分布于我国多地的特殊黏性土,因其具有显著的胀缩性、裂隙性及超固结性等特性,在生活中带来了很多自然灾害和工程建设问题。本文着重从膨胀土的胀缩性、裂隙性、超固结性、渗透性等方面总结了膨胀土及膨胀土边坡的研究现状,并对膨胀土边坡常采用的防治措施进行了归纳总结,最后对膨胀土边坡生态防护研究提出了新思路,为此方面研究提供借鉴。

Expansive soil is a kind of special viscous soil widely distributed in many places in China.Due to its remarkable properties of expansion and contraction,fissure and overconsolidation,it has brought many natural disasters and construction problems.This article focuses on the research status of expansion soil and expansion soil slope from the expansion soil's expansion and contraction,fissure,overconsolidation,and permeability,the common prevention and treatment measures of expansive soil slope are summarized.Finally,according to the characteristics of expansive soil,some new ideas of ecological protection of expansive soil slope are put forward.
