Introduction

After a severely destructive earthquake occurs, quickly and accurately determine the type of earthquake disaster, the extent and scope of the earthquake disaster, is the earthquake emergency rescue command and operation. Important basis for movement. Remote sensing technology has the characteristics of all-time, all-weather, and not affected by the earthquake damage in the disaster area. Therefore, after the earthquake, the earthquake should be rescued. Aid China can quickly obtain information on the disaster situation in earthquake-stricken areas in a comprehensive and macroscopic manner. There are many types and wide distribution of earthquake disasters, different types of disaster information extraction, There are obvious differences in the evaluation objects and methods, and it is difficult to adopt a single standard to regulate. For the coordinated, orderly, efficient and accurate extraction and evaluation For different types of earthquake disasters, it is necessary to standardize the methods, indicators, procedures and results of remote sensing evaluation. Remote Sensing Evaluation" series of standards. This standard is based on a large number of remote sensing-based road seismic damage information extraction and evaluation research results in the past two decades, and summarizes many times at home and abroad. Developed on the basis of experience in remote sensing assessment of earthquake damage to highways. This standard refers to GB/T 24336-2009 "Earthquake damage of lifeline engineering The road damage classification method in the "Classification", while considering the feasibility of using remote sensing technology for highway seismic damage assessment, The degree of damage is divided into three situations. "basically intact", "partially damaged" and "destroyed". Among them, "basically intact" corresponds to GB/T 24336-2009 In the road damage level, "basically intact" and "slight damage", "partial damage" corresponds to "medium damage" and "severe damage", and "destroyed" corresponds to "destroyed". Bad". As the evaluation research of highway components that are not directly visible in remote sensing images of tunnels, culverts, etc. is not yet mature, this standard does not provide Corresponding assessment content. Earthquake Disaster Remote Sensing Assessment of Highway Earthquake Disaster

1 Scope

This standard specifies the content, method and result expression of highway seismic damage assessment based on remote sensing. This standard applies to the use of remote sensing to carry out road seismic damage assessment.
