摘要
高原多年冻土地区工程施工中,需要通过相应的工程结构和工程措施控制多年冻土的活动层(季节融化层)变化,使其上路基的运营变形控制在允许范围内.在介绍青藏高原地区多年冻土工程特性基础上,结合工程具体施工实践,针对冻土的冻融特性和多年冻土区的铁路路基各种处理类型的工作原理及施工工艺进行了简要阐述.
During the project construction of Qinghai provincial local railway from Caidamu to MUli,the corresponding engineering structure and the mechanical control measure are needed to control muti-year frozen earth active layers change,in order to make the displacement operation controlled within permission scope.With the project concrete construction practice,the paper introduces muti-year frozen earth project characteristic,the principle of work and construction craft of processing plan of railway bed in Qinghai-Tibet plateau area.
