青藏铁路环境与地震灾害
|
摘要
从昆仑山口西 8.1级地震、青藏高原地震带、活动断裂带入手 ,讨论了青藏高原地区大地震活动规律 ,指出东昆仑山断裂带东 -西大滩段将是发生大地震的最危险地段 ,唐古拉山到拉萨一带既是大震危险区段 ,又是强震频发区段。分析了青藏铁路穿越区域面临的地震灾害 ,提出了青藏铁路防震减灾对策和措施。
Large earthquake activity in the Qingzang Plateau was discussed based on west to Kunlun Mountain Pass Ms 8.1 earthquake, earthquake belt and active fault. It is postulated that the future large earthquake may be occurrence on the Dongdatan-Xidatan segment of the Eastern Kunlunshan Fault, also the future large earthquake and strong earthquakes may be occurrence on the section of the Tanggulashan-Lasa of Qingzang railway. The occurrence of future earthquake disasters along Qingzang railway is analyzed. Then the authors pointed out some efficient earthquake disaster reduction countermeasures suited for this area.
