摘　　要： 通过对宜宾市金沙江沿岸边坡的工程地质情况进行考察,发现岸坡稳定受金沙江水位升降影响很大。为了研究金沙江下游库岸边坡在各荷载组合工况下的稳定性,以金沙江干流下游左岸两个典型边坡断面为例,采用传递系数法计算了6种不同工况下库岸边坡的稳定系数。结果表明:A-A′断面在6种工况下均处于稳定状态;B-B′断面在工况1~工况4时均处于稳定状态,在工况5时处于基本稳定状态,而在工况6时稳定系数仅有1.008,处于欠稳定状态。计算成果可为后期有关部门设计合理的边坡治理措施提供参考。 Through the investigation of engineering geology of Yibin city Jinsha River along the slope. The slope stability found that has great influenced by Jinsha River water level fluctuation. In order to study the stability of the lower reaches of the Jinsha River bank slope in the load combination, taking two typical slope section of Jinsha river downstream on the left bank as example, transfer coefficient method was used to calculate six different operating conditions of the bank slope stability coefficient. The results show that the A-A′ section is in stable state of the six conditions; the B-B′ section in no.1~no.4 working conditions is in stable state, and in stable state at no.5 case, but in no.6 condition with stability coefficient is only 1.008, which is in less stable state. The results can provide a reference for the relevant departments in the design of reasonable slope treatment measures.
