REGIONAL CRUSTAL STABILITY EVALUATION IN BEIJING-ZHANGJIAKOU AREA
摘要
Abstract
On the basis of field investigation and extensive collection of information,the main factors of controlling and influencing regional crustal stability and the coupling action of internal and external dynamic geology are analyzed.Active fracture,seismicity and deep geophysics are selected as the main influencing factors of regional stability.At the same time,11 factors,including engineering rock group,topography and surface geological hazards,are selected as evaluation factors and assigned according to category.The regional crustal stability evaluation model is established by multi-factors weighted superposition analysis method.Based on the GIS platform,the regional crust stability in BeijingZhangjiakou area is quantitatively evaluated,in which the research region are divided into 4 grades,including stable region,substable region,subunstable region and unstable region.According to the evaluation results of regional crustal stability,relevant suggestions are put forward for the construction and operation of the Beijing-Zhangjiakou high-railway,Yun Ding Shan Ski Slope and Shi Jing Long Ski Slope,which provides the basis for territorial planning of Beijing-Zhangjiakou area.关键词
