| 摘 要： | 研究目的:黄土边坡剥落病害威胁铁路的安全,破坏边坡的生态环境。依据太中银铁路边坡实际调查资料,对黄土边坡剥落的分布特征及其特点进行了深入研究,根据剥落的形态对其进行科学分类,查明其发育规律,同时对其形成机理也作了初步解释,以便为黄土边坡剥落病害的下一步研究打下基础,为铁路边防治工程提供依据。研究结论:太中铁路沿线黄土高边坡剥落形式可分为片状剥落、层状剥落、古土壤层碎块状剥落、厚块状剥落、表层结皮剥落等几种。太中银铁路沿线边坡剥落现象分布呈现一定规律性:剥落多发生在坡面中下部,坡率越大越易发生剥落、存在极限坡率,剥落病害发生的向阳性和向风行。简要分析了剥落的机理及形成原因。

| Abstract: | Research purposes: The spallation disease of loess cutting slope threatens the safet y of railway and destroys the ecological environment.According to the survey data of the slope of Taiyuan-Zhongwei-Yinchuan Railway,the distribution features and characteristics of the spallation of the loess slope are studied.The spallation styles are sorted to find the development regularity of spallation and preliminarily explane the formation mechanism of the spallation for the purposes of laying foundation for treating... |
