摘要:

四川省芦山“4·20” 7.0级强烈地震发生后,次生地质灾害造成多处公路损毁,快速、准确地监测公路灾情,是应急救灾一项基础而重要的工作。遥感影像信息提取是获取公路灾情的一种有效途径。利用震后机载航空影像与国产卫星影像,结合交通运输部相关基础数据,对公路灾情开展了监测与评估。在公路周边共发现433处地质灾害点,灾害类型以崩塌为主。其中对公路已造成影响的灾害点197处,损毁公路总长度约10 km。另有潜在危险性较大的灾害点63处,对公路构成严重威胁,需注意加强防范。经实地验证,公路灾情信息提取结果真实可靠。信息提取与分析结果已分别在震后第二天和第三天上报到交通运输部,为高效地组织开展公路抢修保通提供了科学的依据。

Abstract:

After the 7.0 magnitude Sichuan Lushan earthquake occurred on Apr.20th,2013,the secondary geological disasters caused many damages of highway.It was an important and basic job of emergency relief for highway disaster monitoring fastly and accurately.There was a mature and effective way of obtaining highway disaster information based on remote sensing images and information extraction technology.Utilizing domestic remote sensing satellite images as well as airborne aerial images acquired by Institute of Remote Sensing and Digital Earth,Chinese Academy of Sciences,it focused on highway disasters monitoring with image\|based visual interpretation and analysis methods.After information extraction,433 geological disasters were found around roads and collapse was the main types of disaster.197 disasters have impacted highway and the total length of damaged sections was about 10 km.Meantime,there were 63 disasters became a serious threat to highway,which should be paid attention to analyse.The field investigation proved the road disaster extraction results were reliable.The highway disaster monitoring result was provided to the Ministry of Transport of People’s Republic of China within two days after the earthquake,and it was a sufficient basis for carrying out road repair scientifically and effectively.

Key words: Lushan earthquake    Geological disaster    Highway disaster    Remote sensing
