Regional engineering geological condition evaluation in the Sichuan-Xizang traffic corridor
摘要
Abstract
The regional engineering geological conditions are the important guarantee for geological safety of major engineering planning and construction.The Sichuan-Xizang traffic corridor is located in the eastern Qinghai-Xizang Plateau,and passes through the zone with the most complex terrain and geological structure all over the world,and faces the extremly complex regional engineering geological environment.In order to respond to the geological safety requirements of major engineering planning and construction,this paper takes the major linear project regions in the Sichuan-Xizang traffic corridor as the study area.On the basis of summarizing and analyzing the regional geological settings,the regional engineering geological condition evaluation is completed by using the GIS analytical hierarchy process and 9 geological environment factors,and the regional engineering geological conditions are divided into 4 levels:good,relatively good,moderate and poor.The results show that the active faults are the most unfavorable factors of engineering geological conditions,followed by terrain relief and geo-hazard susceptibility.The areas with good engineering geological conditions are far away from active faults and deep canyons,and are distributed in the blocks and strips between active faults and deep canyons.The areas with poor engineering geological conditions are mainly distributed in the faut zones and alpine and canyon regions.The outstanding performance is that they are relatively close to strongly active faults,especially the regions with intersection of multiple faults.The research results can provide scientific support for the geological safety of major engineering planning in the Sichuan-Xizang traffic corridor.关键词
