摘要

采用灰色关联度分析法对红层软岩的矿物成分、化学成分、崩解试验等数据进行了分析。分析表明

水理特性不稳定的粘土矿物始终是影响软岩崩解的主要因素之一

而不同的化学成分对红层软岩崩解性的影响程度不同。通过以纯水、MgCl2

FeCl3

NaCl

CaCl2盐溶液作为红层软岩岩块浸泡液的崩解试验

说明纯水浸泡下软岩的崩解性最强

而所选3种盐溶液对所选红层软岩样品的崩解性均有抑制作用

其中又以CaCl2抑制作用最强。在此基础上提出公路施工中填筑前以浇水作为加快红层软岩崩解

填筑压实中以掺入石灰作为抑制软岩崩解路用控制方法。

Abstract

By using the grey correlation method

the experimental data of chemical ingredients and slaking index are analyzed. Analysis show that the unstable clay minerals always have the highest influence on the slake property of soft rock; and different chemical ingredients have different influences on the slake property. Pure water

sodium chloride

calcium chloride and ferric chloride solutions are used as a slaking fluid to test the slaking property of a selected specimen. Results show that the selected specimens have greater slake intensity in pure water while less in the three selected salt solutions

especially in calcium chloride solutions. Based on those analysis and study

the slake control method of red beds soft rock used in road construction is to water on the red beds soft rock before construction to fast its slake and mix lime to soft rock when construction to depress its slaking.
