摘要
通过野外实地调查发现,青藏工程走廊(青藏公路74—84道班段)多年冻土区发育有次生不良地质现象,如厚层地下冰、热融滑塌、热融沉陷、热融湖塘、冰锥(冰丘、冰幔)等。基本查明了不良地质现象的危害对象,初步探讨了地质环境与不良地质现象间的关系。为工程安全运行、工程良好维护及地质环境保护提供了地质依据。
Based on the field investigation,secondary bad geological phenomenon appeared along the Qinghai-Tibet Project( 74 to 84 class along the Qinghai-Tibet highway),such as thick layer underground ice,thaw slumping,thaw subsidence,thaw ponds,ice pitons,etc. This paper finds out the hazard objects,discusses the relationship between geological environment and bad geological phenomenon,and provides geological basis for the safe operation,engineering maintenance and geological environmental protection of this project.
