保沧公路沧州西至小园段改建工程安全性研究

Research on safety of west Cangzhou- Xiaoyuan section,Baocang Highway reconstruction engineering

保沧公路沧州西至小园段现为二级路,交通量压力大,车辆阻塞,事故频发。改造为双向四车道,一级公路标准。改建项目下穿京沪铁路,与多条等级公路平交、立交。考虑交通情况、自然条件、设计、建设、环境等多方面因素后,对工程安全性进行分析,为安全生产提供依据。

West Cangzhou Xiaoyuan section, Baocang Highway is secondary road, with big traffic pressure, traffic jam, and frequent accidents. Transformed to four lanes bothway, the stand is first class highway. The redevelopment project under neath pass the Beijing Shanghai railway, and cross and interchange with muhiterm roads. Considering the traffic condition, nat ural condition, design, construction and envronmental factors, analyzed engineering safety, provide basis for safety production.
