青藏铁路建设期青藏公路(格拉段)整治改建工程的冻土环境影响与对策

Impacts on Permafrost Environment and Countermeasures of the Reinforcement and Rebuilding of the Qing-Zang Highway During the Building Period of Qing-Zang Railway

青藏铁路建设期间(2001-2006),大量人员、材料、设备和生活物资的运输都依赖于青藏公路,使得青藏公路格尔木至拉萨段(简称格拉段)的交通量大大增加,对公路路面和桥涵的承载能力带来严峻考验。对青藏铁路建设期青藏公路整治改建工程作了简要的介绍,并从冻土环境的角度分析公路整改工程与冻土环境的相互影响,并提出了相应的环保措施建议,为青藏公路整改工程的决策提供依据。

During the building period of the Qing-Zang Railway （2001-2006）, the Qing-Zang Highway plays an important part in transporting materials, machines and workers for the railway building. The reinforcement and rebuilding project of Qinghai-Xizang Highway is very important for Qing-Zang railway building. This project has impacts on the permafrost environment. Mutual impacts between the highway and permafrost environment are discussed. Some measures and advice are given for the decision-making of the proiect to avoid some environmental problems.
