摘要: 湿陷性黄土是一种对水十分敏感的不良土质,以其为介质的边坡在山西地区广泛分布,此类边坡地质灾害频频发生。本文以山西省临县某已失稳的湿陷性黄土边坡为研究对象,通过现场详勘,解释了由水引起的湿陷性黄土内部结构强度的削弱及外部降雨因素对于边坡的影响,从而得出该边坡发生破坏的机理。同时在华宁岩土软件进行分析计算的基础上,提出了有针对性的失稳边坡加固治理方案,并强调了湿陷性黄土边坡做好边坡排水的重要性。

Abstract: Collapsible loess is a typical problematic soil which is very sensitive to the moisture content. The collapsible loess slopes are widely distributed in Shanxi, and geological hazards are frequently occurred. This paper presents the stability evaluation and remediation results of a failed loess slope in Linxian County, Shanix Province. A geotechnical investigation program was conducted at the failed slope site. It is evident that the intrinsic strength of the loess slope weakened by the infiltration of surface water from the precipitation. The failed slope was analyzed by using Huaning Geotechnical Engineering software and the remediation scheme was then proposed. The case history indicates that the proper drainage system is critically important for the stability of the loess slopes.
