摘要
基础上，针对膨胀性岩石的复杂性和边坡病害的发育程度，采用数学统计分析方法，建立了以岩粉自由膨胀率（Ｆｘ）和岩石干燥饱和吸水率（Ｒｄｗ）为指标的岩石膨胀性综合评价标准，提出了膨胀性岩石堑坡工程的设计原则。
Based on a lot of field geological investigation, sample test and analysis research for the swelling rock on cut slope of several railway lines in China, according to the complexity of swelling rock and the development of slope defects, a comprehensive evaluation standard for rock swelling property has been established, which has the relationship between the free swell of rock silt (Fx) with the dry saturated hydroscopic moisture ratio of rock (Rdw). The engineering design rule for the swelling rock cut slope has been put forward also in this paper.
