Stability Analysis of Duchuanbian Collapse

Article Preview

Abstract:

Duchuanbian collapse is located inside Micangshan avenue in Nanjiang county, Sichuan province, consisting of 6 dangerous rock bands. It is in a basically stable state overall now, with partial area in a semi-stable or unstable state. Qualitative analysis is carried out in stereographic projection method taking 1st dangerous rock band of Duchuanbian collapse for example, so as to understand the structure feature of slope rock mass, and judge it may occur collapse in falling type.And then static force analysis method is used for quantitative calculations, thus determining that 1st dangerous rock band is in semi-stable state under natural condition, and it may occur collapse under action of torrential rain, earthquake and other unfavorable factors. Therefor, it requires to take reasonable measures for comprehensive treatment.
