【摘要】 主要研究膨胀岩的膨胀特性,用软岩膨胀测定仪对重塑试件和原岩试件进行软岩膨胀率的测定,根据大量的软岩膨胀性试验成果,找出了软岩膨胀应力与线膨胀率、线膨胀最终饱和含水率特性曲线,泥质岩干燥饱和吸水率与蒙脱石含量特性曲线的相关分析结果,采用风干或烘干的不规则试件吸水率的大小作为对膨胀岩的判别和评价的依据。更多还原

【Abstract】 Swelling properties of swelling rock are discussed in this paper, and soft rock swelling radios of samples are measured by the soft rock swelling instrument. The characteristic graph of soft rock linear swelling ratio and swelling stress and final water saturation ratio ,and related analysis results of the ratio about mud rock dry saturated absorbed water ratio and the quality contained montmorillobnite are obtained based on a large number swelling experimental results about soft rock are got.. the criterion of swelling rock by the size of the ratio irregular test sample absorbed water in air-dry or dry condition are also got.更多还原
