摘要/Abstract

摘要： 采用均匀设计安排试验，运用灰色理论中的灰色关联分析考察边坡稳定性影响因素的主次。结果表明，边坡稳定性影响因素的敏感性由大到小依次为：粘聚力、内摩擦角、重度、预应力、锚索间排距、锚索长度、锚固段长度、锚固角。可见，岩体的抗剪强度指标是影响边坡稳定性的最重要参数，其次是岩体的容重，而预应力锚索的设计参数对边坡的稳定性也有一定影响。这一分析结果为边坡开挖设计和加固方案的优化提供了重要依据。

Abstract: The uniform design was used to design the experiments, and the grey correlation analysis of grey theory was used to analyze the primary and secondary factors of slope stability. The results show that sensitivity factors of the slope stability are cohesion, internal friction angle, unit weight, prestress, inter-row spacing of the anchor, the length of cable, length of bond part and anchorage angle which take turns from the most important to less. It is easy to see that the shear strength parameters of rock are the most important factors that affect slope stability, next is the unit weight; and the design parameters of prestressed anchorage also have effect on slope stability. The results show a profound impact on design of the slope excavation and optimization of the reinforcement.

Key words: uniform design, grey theory, grey-correlation analysis, slope stability
