随着我国西部大开发战略的实施,近年来广西红层地区工程建设逐渐增加,本文以红层岩组为基础,对广西地区红层分布进行分析,认为十万大山地区和桂东-桂东南区域分布较为密集。通过物理化学试验及力学试验对红层泥岩进行工程特性统计分析,得出上述区域泥岩膨胀性和崩解性特征,并通过击实特性、CBR承载比、软化系数等指标得知两区域泥岩填料级别主要为C3和C2,从而为相关红层区域工程建设提供一定的理论依据。
With the implementation of the strategy of western development in our country, the construction of red beds in Guangxi Province has been gradually increasing in recent years. Based on the red beds and the lithofacies, the distribution of red beds in Guangxi is analyzed. Regional distribution is more intensive. Through physical and chemical tests and mechanical tests, the engineering characteristics of red mudstone were statistically analyzed, and the expansiveness and disintegration characteristics of mudstone in these areas were obtained. According to compaction characteristics, CBR bearing ratio, softening coefficient and other indicators, The main grades are C3 and C2, so as to provide certain theoretical basis for the construction of the relevant red layer area.
