摘要
文章采取层次分析和综合评判的三级区划方法,分别考虑冻土的类型、热稳定性和含冰(水)量,将西大滩至安多间的青藏工程走廊划分为3个工程地质区、20个亚区和51个地段,按区(段)简要评价了冻土工程地质条件和寒区环境。文章对青藏工程走廊进行了较全面的冻土工程和寒区环境工程地质综合评价,能为工程设计、施工和运行维护、融冻灾害整治和环境管理提供科学依据。
The Qinghai-Tibet Engineering Corridor （QTEC） is divided into three zones, 20 subzones, and 51 sections of engineering geology based on the regionalization at three levels using similarity, differential and statistical analyses. Types, thermal stability and ice （water） contents （I（W） Cs） of frozen ground are taken into account in the division in frozen ground environmental engineering geology （FGEEG） zones, subzones and sections, aiming at reflecting present conditions in FGEEG and cold regions environments. Each zone, sub-zone and section is evaluated for engineering design and hazards mitigation. In this paper, the authors comprehensively assesses the environmental engineering geology in frozen ground and cold regions along the QTEC for the first time, reflecting the latest advances in the pertinent studies, which provide more a detailed scientific base for engineering design, construction, operations and maintenance, mitigation and environmental management.
