河南省西峡县石界河乡通渠村滑坡成因分析及稳定性评价

Cause analysis and stability evaluation of Tongqucun landslide in Shijiehe Township of Xixia County,Henan Province

河南省西峡县雨量充沛,容易引起滑坡地质灾害。本文以通渠村滑坡为研究对象,首先通过资料收集和现场详细调查,查明滑坡区的地质环境条件。通过钻探、槽探和井探等勘查手段,查明滑坡的基本特征和空间形态。对滑坡进行成因分析,再根据试验数据统计、经验类比及反算值综合确定滑坡岩土体物理力学参数。最后通过传递系数法对滑坡的稳定性进行计算。

Xixia County in Henan Province is prone to landslides due to its abundant rainfall.In this paper,the Tongqucun landslide is taken as the research object.Firstly,the geological environment conditions of the landslide area are found out through data collection and in-situ detailed investigation.The physical and mechanical parameters of rock and soil mass are determined synthetically according to the statistics of test data,empirical analogy and back calculation value.
