摘　　要：目的研究清远—连州公路岩质边坡结构面特征及其组合关系对边坡稳定性的影响。方法采用普遍测网法实测该公路沿线边坡结构面,分析结构面的组合关系对边坡稳定性的影响;采用“赤平投影结构数据分析软件包”对结构面的参数进行统计分析;采用结构面二维网络模拟程序进行模拟。结果得到结构面产状和边坡坡面产状关系的统计图和二维网络模拟图。结论清连公路结构面组合关系对边坡稳定性影响显著,结构面参数研究对边坡稳定性评价意义重大。Aim To research the action of rocky slope structural plane and its combination on the slope stability in Qingyuan-Lianzhou Highway, Guangdong Province, China. Methods Using survey grid method to measure structural planes alongside the highway to analyze effect of the combination of structural plane on slopes stability; utili- zing the structural equator projection data analysis package to state the parameters of structural plane; simulating with structural 2D network simulation program. Results Statistic graphics and 2D network simulation graphics on relation between structural plane occurrence and the occurrence of slope were derived. Conclusion The relations between structural planes is influential on slope stability, and the distribution pattern of structural plane in slope was identified.
