摘要
文章列举了中国西部山区地震对道路、桥梁和隧道造成直接破坏和地震次生灾害造成间接破坏的类型,分析了破坏的原因。山区地形陡峭,地质条件较差,地方经济水平有限,设计未考虑抗震或者抗震等级不足,施工技术水平相对欠缺是造成山区交通设施震害格外严重的原因。
The paper lists the types of direct and indirect damages to roads,bridges,tunnels caused by the earthquake in mountainous areas in the west of China,and the reasons for damages are analysed. Due to the steep mountain terrain,poor geological conditions,the limit of the local economic development level,the lack of design for anti-seismic or an inadequate consideration of seismic level along with the relative low level of the construction technology,the damages from the earthquake are particularly severe in mountain areas.
