“8·8”舟曲特大山洪泥石流灾害的发生在偶然中有其必然性,地质环境条件脆弱是导致灾害发生的主要原因。南桥滑坡位于舟曲县城白龙江南岸,是“8·8”泥石流灾害发生后应急调查确定的第一批治理项目8处灾害点之一,综合定名为牵引式—中型—堆积体滑坡。该滑坡变形活动悠久,属老滑坡,活动规模大、变形复杂、潜在威胁性大。本文旨在通过反演、试验及工程类比手段综合确定强度参数进行滑坡稳定性分析,定性辅以定量确定其稳定程度,针对性地提出防治方法及其对策。
Occurrence of debris flow disaster in Zhouqu has its inevitability by chance. The fragile geo-environmental conditions are the main causes of disasters. Located on the south bank of Bailongjiang in Zhouqu County, Nanqiao landslide is one of the eight disaster points of the first batch of governance projects identified by the emergency investigation after the occurrence of the debris flow disaster. It is generally named as a traction-medium-stacked landslide. This landslide has a long history of deformation and is an old landslide with a large scale of activities, complicated deformations and great potential threats. The purpose of this paper is to determine the stability of the landslide by comprehensively determining the intensity parameters by means of inversion, experiment and engineering analogy. The stability of the landslide is quantified by qualitative analysis, and the prevention and cure methods and countermeasures are pointed out.
