摘　　要：边坡稳定性受多种内外因素的综合影响,正确地认识各影响因素的特征及其对公路边坡稳定性的影响程度,有助于对边坡进行合理的评价,并采取经济有效的防护措施。本文在现场工程地质调查和文献调研的基础上,搜集了622个典型山区公路边坡的地质资料及灾害资料,建立了山区公路边坡地质灾害数据库,统计了各影响因素与边坡失稳频度的关系。统计结果表明,失稳频度能较好的体现边坡影响因素与边坡稳定性状态的关系。Slope stability is affected by multiple internal and external factors.Based on the engineering geological investigation in the field and literature research,the geological data of 622 typical slopes along the mountainous highway are collected,and a slope geological hazard database is established.According to the database and literature results,a statistical analysis is made on the relationship between instability frequency of slope and influencing factors for slope stability.Results show that the instability frequency of the slope can better show the relationship between the state of slope stability and its influencing factors.
