在结合青藏公路设计及维修养护方面的经验教训的基础上,对青藏公路、铁路引起的冻土环境问题并由此可能引发的路基病害进行简要分析,指出冻土环境保护总的原则为冷却地基冻土、增加地基土冷储量、减少热量输入。提出青藏公路、铁路在设计、施工及运营管理方面相应的工程防治措施。
Based on the experience and lessons from the design and maintenance of the Qinghai-Tibet Highway, this paper briefly analyzes the permafrost environmental problems caused by the Qinghai-Tibet Highway and the railway and the possible causes of roadbed diseases. It points out that the general principle of the permafrost environmental protection is to cool the foundation Frozen soil, increasing soil cold storage, reduce heat input. Put forward the corresponding project prevention and control measures in the design, construction and operation management of the Qinghai-Tibet Highway and the railway.
