摘要: 基于可拓理论,从3个层次5个指标建立了边坡稳定性评价指标体系,研究了内摩擦角和黏聚力对边坡稳定性的影响,给出了抗剪强度参数与安全系数之间的数量关系.研究结果表明:随内摩擦角和黏聚力的增大安全系数呈线性增大,且内摩擦角对安全系数的敏感性明显大于黏聚力对安全系数的敏感性.最后,基于安全、经济、高效的原则,采用锚杆措施对辽宁省小盘岭边坡进行加固处理.

关键词: 可拓理论, 抗剪强度, 安全系数, 稳定性分析, 稳定性控制

Abstract: An evaluation index system on slope stability using three levels and five indexes were established on the basis of the extension theory to study the effect of internal friction angle and cohesion on the slope stability. The quantitative relation between the shear strength and the safety factor was given. The results showed that the safety factor increases linearly with the increase of the internal friction angle and the cohesion, and the internal friction angle is more sensitive than the cohesion to the safety factor. Finally, the Xiaopanling slope in Liaoning Province was reinforced by bolt based on the principles of safety, economy and efficiency.

Key words: extension theory, shear strength, safety factor, analysis of stability, control of stability
