【摘要】：G42沪蓉高速公路奉节至云阳段是国家“7918”高速公路网上海至成都高速公路之一段,长约71km,穿越渝东北三峡库区。受特殊的地形、地质和水系条件等的制约,G42沪蓉高速公路奉云段地形地势复杂,环境条件多变,设计建造了大量的分离式路基,多与桥、隧相连,且桥隧比例较高:分离式路基段长度累计达到了14.47km,约占路线总长度的20.37%,加上约60%的桥隧比,G42高速公路奉云段分离式路段比例超过了80%。山区高速公路分离式路段给高速公路事故现场的应急救援造成了很大的困难。针对G42高速公路奉云段分离式路基和沿线桥隧分布情况,分析分离式路基段的运营安全特点,重点开展了以下方面的研究:(1)根据G42高速公路奉云段分离式路基路段及其与桥隧路段的组合情况,划分路段管理单元。(2)分析高速公路分离式路基路段可能突发事件类型及严重程度划分,研究G42高速公路奉云段突发事件联动控制策略。(3)详细地分析了高速公路交通事故应急救援资源配置需求,制定了G42高速公路奉云段交通事故应急救援资源的合理配置方案;(4)调查G42高速公路奉云段沿线路网现状,建立应急通道路网系统,制定了高速公路分离式路基段交通事故发生时应采用的交通管制措施和交通引导方案。(5)全面评价分离式路基段及其与桥隧路段的组合对G42高速公路奉云段运营管理的影响,积极探索大面积、长距离分离式路基的运营管理关键技术。通过研究成果的应用,降低了突发事件对交通的影响,增强了突发事件下应急保障能力,提高了运营管理水平,有效促进了G42奉云高速公路的安全畅通。
[Abstract]:The section from Fengjie to Yunyang of Hurong Expressway G42 is a section of the national "7918" highway network from Shanghai to Chengdu, which is about 71 km long and passes through the three Gorges Reservoir area of northeast Chongqing. Restricted by the special terrain, geology and water system conditions, the terrain of Fengyun section of the G42 Hu-rong Expressway is complex and the environmental conditions are changeable. A large number of separate subgrade have been designed and built, most of which are connected with bridges and tunnels. And the ratio of bridge and tunnel is high: the cumulative length of separated subgrade reaches 14.47 km, accounting for 20.37% of the total length of the route, plus about 60% of the bridge and tunnel ratio is more than 80% of the separated section of G42 freeway. The isolated section of mountain expressway has caused great difficulties to the emergency rescue of expressway accident site. In view of the distribution of separated subgrade and bridge and tunnel along Fengyun section of G42 expressway, the operation safety characteristics of separated subgrade section are analyzed. Focusing on the following aspects of research: 1) according to the G42 freeway Fengyun section of the separated subgrade section and its combination with the bridge and tunnel section, Division of section management unit. (2) Analysis of the type and severity of possible emergencies in separated roadbed sections of expressway. In this paper, the emergency control strategy of G42 freeway, Fengyun section, is studied, and the need of emergency rescue resource allocation for expressway traffic accident is analyzed in detail. The rational allocation scheme of emergency rescue resources for traffic accidents in Fengyun section of G42 Expressway is established. The investigation of the current situation of the road network along the Fengyun section of G42 Expressway is carried out, and the road network system of emergency passageway is established. The traffic control measures and traffic guidance scheme for separated roadbed section of expressway are formulated. The comprehensive evaluation of the influence of separated subgrade section and its combination with bridge and tunnel section on the operation and management of Fengyun section of G42 expressway is made. Explore the key technology of operation and management of large area and long distance separated roadbed. Through the application of the research results, the impact of emergencies on traffic is reduced, the ability of emergency support under emergencies is enhanced, the level of operation management is improved, and the safety and smooth flow of G42 Fengyun Expressway is effectively promoted.
