摘要: 怒江州贡山县丙中洛镇某不稳定斜坡下方居住有23户共71人,该斜坡一旦失稳,将对这些居民的生命、财产安全构成威胁,威胁资产约90万元。在现场调查与理论分析的基础上,并依据基本的地质环境,对怒江州贡山县丙中洛镇某不稳定斜坡基本特征与变形规律开展了分析与研究。研究结果表明:BW不稳定斜坡稳定性好,斜坡天然及暴雨工况下处于基本稳定状态;BW1-1稳定性较差,斜坡天然状态下处于欠稳定状态,暴雨及地震工况下处于不稳定状态,因此建议治理措施重点应在BW1-1部分。

关键词: 不稳定斜坡, 稳定性, 发展趋势

Abstract: There are 23 households with 71 people living under an unstable slope in Bingzhongluo Town,Gongshan County,Nujiang Autonomous Lisu Prefecture.It will pose a threat to the lives and property of these residents,and it will be of great danger when the slope failure time comes,about 900000 yuan worth of threatened assets.Based on the field investigation and theoretical analysis,and according to the basic geological environment data,this paper analyzes and studies the basic characteristics and deformation laws of an unstable slope in Bingzhongluo Town,Gongshan County,Nujiang Autonomous Lisu Prefecture.The results show that:BW1 unstable slope has good stability and is in a stable state under natural and heavy rain conditions;BW1-1 has poor stability and is not stable in natural conditions and is unstable under heavy rainfall and earthquake conditions.Therefore,it is recommended that the governance measures should be focused on the BW1-1 section.

Key words: unstable slope, stability, development trend
