| 摘 要： | 山区二级公路受地形影响较大，路侧危险，线形设计指标较低，道路线形设计的协调性相对较差。由于二级公路的交通管制力度弱，当地居民随意在道路主线上搭建接入口，这些接入口严重影响了道路的服务水平和安全状况。从道路平面、纵断面、横断面及其他要素选取指标分析山区二级公路接入口的安全状况，应用层次分析法对接入口进行风险评价，针对评价结果采取相应的安全改善对策，并依托云南施孟公路，用层次分析模型对实际接入口进行安全评价。

| Abstract: | Mountainous second-grade highway is seriously affected by the terrain.The roadside is very dangerous and the road alignment design indexes are very low.The coordination of the road align-ment design is relatively poor.The traffic control of mountainous second-grade highway is weak,and the local residents are free to build the road access on main road.access has a serious impact on the level of service and security situation of the road.This article analyzes the security situation of the access in mountainous second-grade highway from the indexes of road plane,longitudinal,cross-sectional and other elements.Using AHP to evaluate the risk of the accesses,and take appropriate safety improvement meas-ures.Relying on the Yunnan ShiMeng highway,using the AHP model to evaluate the actual access. |
