【摘要】 基于有限单元理论,对贵州毕节仓库边坡稳定性进行了研究,并着重分析土体内摩擦角、粘聚力和重度对边坡失稳的贡献程度。研究表明:土体重度、土体粘聚力及内摩擦角对边坡稳定性影响显著。随着土体粘聚力、内摩擦角的增大,边坡稳定安全系数成线性增大趋势;而随着土体重度的增大,边坡稳定安全系数则减小。边坡稳定性影响因素中,内摩擦角对边坡稳定影响较为敏感,粘聚力的影响次之,土体重度的影响最小。更多还原

【Abstract】 Based on the finite element theory,the slope stability of Bijie in GuiZhou province is investigated,and the sensitivity of the effects of soil unit weight,soil cohesion and soil angle of internal friction on slope stability are studied.The results indicate that soil unit weight,soil cohesion and soil angle of internal friction have remarkable effect on the slope stability.The slope stability increase with increasing the soil cohesion and soil angle of internal friction;but with the increase of the soil unit weight,slope safety factor is reduced.Among all the influence factors,the soil angle of internal friction is the most sensitive to slope stability and cause the greatest change of safety factor.Based on the result of sensitive factors analysis,the slope engineering can be more effectively guided to deal with main influences factors.更多还原
