| 摘 要： | 通过地表路线地质观测、不同比例尺的活动构造填图及不同深度的地球物理探测，证实青藏铁路沿线发育近南北向活动构造带，表现为活动断层、地壳形变、第四纪断陷盆地、建造、地震活动、温泉线性分布及比较显著的地球物理异常。青藏铁路沿线近南北构造带现今活动性比较强烈，未来尚有增强趋势，能够诱发多种类型的地质灾害，对铁路路基、公路路基和永久建筑产生不同程度的工程危害。

| Abstract: | A nearly N-S-trending active tectonic belt is attested to exist along the Qinghai-Tibet Railway under construction according to surface geological route survey,active tectonic mapping at different scales and geophysical exploration of different depths.The N-S-trending tectonic belt along the railway exhibits evidently active faulting,crustal deformation,Quaternary down-faulted basins,earthquake activity,linear distribution of hot springs and distinct geophysical anomalies and different formations distributed on both sides of it.The N-S-trending tectonic belt also shows relatively strong tectonic activity at present and a trend of enhancing of the tectonic activity in the future and can induce many kinds of geological hazards and jeopardize the railway bed,highway bed and permant engineering works to different degrees. |
