中国西部天山公路雪崩工程治理研究

Research on Engineering Prevention and Management of Highway Avalanche on Western Tianshan Mountains of China

天山西部的国道218线雪害典型,各种雪崩发育过程清晰,内容丰富。虽然每年道路雪崩表现的程度不同,但雪崩发生的位置基本固定,每隔数年都有一次大的雪崩出现。通过雪害调查,可以摸索出治理与规避雪崩的技术措施,为推广应用奠定基础,最后达到保证国道218线冬季道路畅通或基本畅通之目的。

National highway 218 on western Tianshan Mountains often suffers typical snow disasters,and development process of various avalanches is clear and complicated.Although road avalanches of different degrees may happen annually,position suffering avalanche disaster is basically fixed and one serious avalanche disaster may happen in every several years.Through investigation of snow disasters,technical measures to prevent,control and avoid avalanche can be learned,paving a solid foundation for further promotion and application and reaching the final aim to guarantee the national highway 218 clear or basically clear in the winter.
