摘要
公路边坡工后运营稳定状况紧密关系着交通安全运营,准确评估公路边坡安全风险对于公路边坡的养护、交通安全运营具有重要意义。基于公路土质边坡的坡体几何断面特征、岩土特性等影响因素,考虑边坡失稳滑坡后果影响,提出一套量化的以边坡稳定性和滑坡后果两类共13个风险因子为评判指标的土质边坡安全风险评估方法,可简便、快速、经济地判断边坡的风险状况,结合某高速公路14处土质高填方边坡工程验证了安全风险评估方法的有效性,以期为保障公路的安全运营提供科学依据。
The operation stability of highway slope is closely related to traffic safety operation. It is of great significance to accurately evaluate the safety risk of highway slope for highway slope maintenance and traffic safety operation. Considering that there are more qualitative and less quantitative studies on the assessment of safety risk of highway soil slope,this study is based on the geometric section characteristics of slope body and geotechnical characteristics of highway soil slope,considering the influence of slope instability and landslide consequences,and puts forward a set of quantitative soil slope safety risk assessment methods based on 13 risk factors of slope stability and landslide consequences. Combined with 14 soil high fill slopes of a highway,the effectiveness of safety risk assessment method is verified in order to provide scientific basis for ensuring the safe operation of the highway.
