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。
The stability of slope is affected by the combination of many internal and external factors. It is of great significance to know the characteristics of each influencing factor and its influence on the stability of highway slope properly, which is helpful to evaluate the slope rationally and to adopt economical and effective protection Measures. Based on the on-site engineering geological survey and literature investigation, this paper collects the geological data and disaster data of 622 typical mountainous road slopes and establishes a database of geological disasters of mountainous highway slopes. The influencing factors and the slope failure frequency Degree of relationship. The statistical results show that the frequency of instability can well reflect the relationship between the factors affecting the slope and the stability of the slope.
