摘要研究目的：拟建香日德—花石峡公路位于青海省境内, 全长156. 61 km, 起点在香日德与G109线连接,终点至花石峡与G214线国道连接。其中K 88+ 200~ K 156+ 610段长68. 41 km, 大部分海拔4 000 m 以上,最高在挝卓依垭口, 海拔4 445. 647 m; 本段线路位于青藏高原东部, 多年冻土发育的边缘地带, 本文通过勘察资料分析, 得出沿线多年冻土分布特征并分析其变化规律。
研究结论: 通过对本段线路的勘察资料分析表明: 本段多年冻土和海拔高度有很好的相关性, 主要分布在挝卓依垭山垭口前后海拔4 200 m 以上路段, 局部海拔在4 000~ 4 200 m 湖相沉积细粒土地段存在残余多年冻土。沿线整段多年冻土处于退化状态, 且北坡较南坡年平均低温低, 南坡多年冻土退化严重。
Abstract：Research purposes: The planed X iangride - Huashix iaH ighw ay is located in Q inghai Prov ince, w ith tota leng th of 156. 61 km, Starting in X iangride to connect the G109 NationalH ighw ay, and ending inHuash ix ia to connect G214 N ationalH ighw ay. The sea level elevation o f themost parts o f the section betw een K 88 + 200 and K 156 + 610 w ith to tal length of 68. 41 km is above 4 000m and the highest sea level elevat ion is 4 445. 647m in the Zhuow oy i gap.Th isH ighway is located in the east Q ingha i- T ibet P la teau and the development edge o f of the permafrost area. This paper ana lyzes the d istribut ion characteristics and the change law o f perma frost a long the h ighw ay based on the ana lysis of the surveyed data.
Research conclusions: The ana lysis o f the surveyed data show s the permafrost in this area so closely co rre la tesw ith sea level e levation that the permafrost is m ainly located in the front and rear areas o f Zhouw oy i gap w ith the sea leve lelevation of above 4 200m. There are som e residual perma frost in the area of lacustr ine so ilw ith sea level elevation o f 4 000~ 4 200 m . The permafrost a long the highw ay is in degenerate status and the perma frost on the south slope is degenerated seriously and the temperature of north slope is low er than south slope.
