T/CI 173-2022
Basic Information
Scope
Scope: This document stipulates the working principles, procedures, data requirements, delineation methods, and output formats for the risk assessment of geological disasters in cross-border transportation corridors. This document applies to the risk assessment of geological disasters such as landslides, collapses, debris flows, mine subsidence, land fissures, ground subsidence, and glacial lake outburst floods in areas prone to geological disasters within the cross-border transportation corridors, during the feasibility study phase of various engineering construction and planning projects. Main technical content: 4.1 Purpose and Tasks The risk assessment of geological disasters in cross-border transportation corridors serves to ensure the safety of transportation corridors. The assessment results are used to formulate geological disaster prevention and control plans and road route planning, and to avoid or reduce losses caused by disasters during operation. It provides a foundation for systematic geological disaster prevention and control efforts, with the principles of reducing geological disaster losses and protecting road projects and people's lives and property as the priority. 4.1.1 Based on the geological environmental conditions, geological disaster development distribution characteristics, hazard levels, and triggering factors in the survey area, analyze the disaster formation patterns of geological disasters. 4.1.2 Conduct a preliminary assessment of the susceptibility and risk of geological disasters in cross-border transportation corridors, and prepare relevant maps for geological disaster risk assessment. 4.1.3 Establish a spatial database for geological disaster risk assessment in cross-border transportation corridors. 4.1.4 Propose control measures and recommendations for geological disaster risks in cross-border transportation corridors, providing a foundation for disaster prevention and control management, spatial planning of transportation corr
