Introduction
Numerous site surveys of major earthquakes at home and abroad and analysis of their disaster phenomena show that active faults are the root cause of earthquakes and also earthquake disasters
The culprit. Finding out the exact location of seismically active faults and making a scientific evaluation of their attributes and seismic risk is an earthquake disaster risk assessment
And the important basic work of earthquake disaster prevention. Since the "Ninth Five-Year Plan" period, my country has gradually promoted the detection of active faults.
Great progress has been made in engineering technology, and certain practical experience has been accumulated. The results are in urban planning, land use, engineering construction, and
Earthquake science research and other fields have played an important role.
In recent years, the seismic department has organized and carried out active fault detection technology to sort out the work process, work content and work results.
This framework. In order to standardize and guide my country's active fault detection and application of its results, GB/T 36072-2018 ``Active Fault
Layer Detection”, this standard provides technical requirements for the work content, workflow, technical methods, data management, and output of active fault detection.
The requirements are stipulated. On this basis, further evaluate and analyze various technical methods to achieve detection purposes, and clarify their technical indicators and
Data collection requirements and a standard framework for active fault detection have been constructed.
Seismic structure map is the result of active fault detection work. It is a basic map for studying seismogenic structures in a region.
Identification and division of potential seismic sources play an important role. 1.250,000 is the basic scale for the compilation of seismic structure maps. To 1.250,000 earthquake
The standardization of structural map compilation will greatly promote the improvement of the quality of active fault detection and the application of results.
Active fault detection
1.250,000 seismic structure map compilation
1 Scope
This standard specifies the map compilation process, data collection and arrangement, the content of seismic structure map drawing and
Requirements, drawings, types of results, and requirements for compiling instructions for seismic structure maps.
This standard is applicable to the compilation of 1.250,000 seismic structure maps in active fault detection, and the compilation of seismic structure maps involved in other work.
The system can be used by reference.
