Study on the disaster effect and prevention countermeasures of landslide in Zhouqu fault zone

摘要:
舟曲是我国滑坡灾害最严重的地区之一,其中断裂带滑坡活动频繁,危害巨大。文章在综合遥感、变形监测和现场调查的基础上,研究了断裂带滑坡特征及其灾害效应,提出了风险防控对策。研究表明:(1)断裂带滑坡形态上主要为长条形和簸箕形;滑体、滑床一般为板岩、千枚岩碎块石组成,滑带土为含砾黏土;滑坡具有多级、分块活动特征且块体差异性滑动特征显著;滑坡一般为慢速滑动,具有蠕滑特征;滑坡具有降雨敏感性特征,深层滑坡对降雨响应有明显的滞后性。(2)断裂带滑坡的成灾模式主要为慢速滑动过程中的蠕滑拉裂效应和冲击推挤效应,滑动后的堵江淹没效应、挤压侵蚀效应,以及社会影响效应等。(3)断裂带滑坡规模较大,地层破碎,治理条件差,工程治理措施难以奏效。但其突发性不强,应以管防为主,宜采取用地管控、监测预警、避险搬迁等防治措施,慎用工程治理措施。
Abstract:Zhouqu is one of the areas with the most serious landslide disasters in China, in which the fault zone landslide are frequent and the harm is huge. Based on the comprehensive remote sensing, deformation monitoring and field investigation, this paper studies the reactivation characteristics and disaster-causing mode of fault zone landslide, and puts forward the prevention and control countermeasures. The results show that: (1) the landslide in the fault zone is mainly in a strip shape and dustpan shape; The sliding body and sliding bed are generally composed of slate, phyllite and rubble, and the sliding zone soil is pebbly clay; The landslide has the characteristics of multi-level and block activity, and the differential sliding characteristics of different blocks are significant; Landslide is generally slow sliding and has fluidity characteristics; Landslide has the characteristics of rainfall sensitivity, and the response of deep landslide to rainfall has obvious lag. (2) the disaster modes of landslides in fault zone are mainly creep, tension crack effect and impact push effect in the process of slow sliding, river blocking and flooding effect, extrusion erosion effect and social impact effect after sliding. (3) the landslide conditions are large and the treatment measures are difficult to get together. However, its sudden nature is not strong, so it should focus on management and prevention. The recommended prevention measures are land use control, monitoring and early warning, risk avoidance and relocation, and engineering treatment measures are not recommended.
