| 摘 要： | 下蜀土滑坡是宁镇地区一种常见的地质灾害类型,其具有分布广、数量多、季节性明显、受人为环境影响大等特点。与常规土体滑坡相比,下蜀土滑坡具有土体吸水饱和后强度迅速降低的力学属性,这将导致滑坡的产生具有明显的突变性。以往针对下蜀土滑坡产生原因的研究主要是针对自然未产生滑动的边坡,鲜有从已产生滑动的边坡开展研究分析工作。据此,本文将采用现场调查,室内试验,理论分析和案例对比的方法,对两个典型的下蜀土滑坡的成因机制进行分析。结合滑坡产生的主要因素,从应急和永久两个方面对两个滑坡提出了有效的处理措施,为类似下蜀土滑坡的综合防治提供借鉴和参考。

| Abstract: | Xiashu loess landslide is a common geological disaster in Nanjing-Zhenjiang area. It has the characteristics of wide distribution,large quantity,obvious seasonality and being largely influenced by human environment. Compared with the conventional soil landslide,Xiashu loess landslide has the characteristic of obvious mutation,because the strength is rapidly decreased when the loess is saturated with water. In the past,researchers mainly focused on the unstabilized Xiashu loess slopes,and studies on the landslides are scarce. This paper will analyze the mechanism of two typical Xiashu loess landslides by field investigation,laboratory test and theoretical analysis. According to the main factors leading to the landslides,effective emergent control measures for emergency and permanent of the landslides are proposed. These measures can provide reference for the similar landslide. |
