【摘要】：2015年07月03日,新疆维吾尔自治区和田地区皮山县(37.6°N,78.2°E)发生MS6.5级地震,震源深度10km。本文利用高性能无人机数据采集平台获取灾区高分辨率影像数据,结合地震现场震害调查建立建筑物震害遥感解译特征,采用人工目视解译完成了灾区6个0.01°×0.01°格网评估区房屋类型及损毁程度应急遥感调查,获取测区地震灾情信息。结果表明:测区内房屋结构类型主要包括土木、砖木、砖混结构;倒塌房屋主要为土木结构及个别老旧砖木结构房屋,倒塌和局部倒塌的土木结构房屋占评估区土木结构房屋总数的68%,倒塌和局部倒塌的砖木结构房屋占评估区砖木结构房屋总数的12%;测区砖混结构房屋局部倒塌1间,未倒塌228间,砖混结构显示出良好的抗震性能,对避免人员伤亡和减少经济损失起到重要作用。
[Abstract]:In July 3rd 2015, a MS6.5 earthquake occurred in Pishan County, Hotan region, Xinjiang Uygur Autonomous region. The focal depth of the earthquake is 10km. this paper uses the high performance UAV data acquisition platform to obtain the high resolution image data of the disaster area, and establishes the remote sensing interpretation characteristics of the building earthquake damage in combination with the earthquake site earthquake damage investigation. An emergency remote sensing survey on the types of buildings and the degree of damage in 6 assessment areas of 0.01 掳脳 0.01 掳grid in the disaster area was completed by artificial visual interpretation. The results show that the structural types of buildings in the survey area mainly include civil engineering, brick, brick and concrete structure; The collapsed buildings are mainly civil structures and individual old brick buildings, and the collapse and partial collapse of civil structure houses account for 68% of the total number of civil structure houses in the assessment area. The masonry structure houses which collapsed and partially collapsed accounted for 12% of the total number of brick and wood structure houses in the assessment area. The masonry structure shows good seismic performance and plays an important role in avoiding casualties and reducing economic losses.
