公路运输系统是交通运输系统的重要组成部分,因地震灾害而导致的公路运输系统破坏,必然会影响救援工作的迅速开展。首先分析了地震灾害下公路运输系统破坏及修复的特点,针对公路运输系统所独有的特点建立灾前、灾时和灾后三阶段防救灾系统实施框架;并对地震灾害防救灾过程中,关键交通设施和基本路段的结构性和功能性灾害损坏程度评估等技术进行分析,建立灾时公路设施修复优先度评估指标集,提出灾前、灾时和灾后公路运输系统防救灾目标和策略。
The road transport system is an important part of the transport system. The destruction of the road transport system caused by the earthquake disaster will inevitably affect the prompt rescue work. Firstly, the characteristics of road transportation system destruction and repair under earthquake disaster were analyzed. According to the characteristics of road transportation system, the framework of disaster prevention and disaster relief system was established in three stages before, during and after disaster. In the process of earthquake disaster prevention and relief, the key Traffic facilities and basic sections of structural and functional disaster damage assessment techniques to establish priority assessment of road facilities in disaster recovery indicators set to raise the pre-disaster disaster and post-disaster road transport system disaster relief goals and strategies.
