花石峡连续多年冻土区湿润性地段路基稳定性模拟分析

Modeling analysis on the heat stability of embankment for the continuous permafrost district with rich moisture in Hua Shixia Valley

摘要: 根据２１４国道花石峡长石头山连续多年冻土湿润性地段的自然地理及地质水文条件，对该区在分别修建不同高度的沥青、水泥混凝土、砂砾路面后路基的稳定性进行模拟分析与试验路段的实测性对比。

Abstract: The heat stability of embankment on the continuous permafrost district of Chang Shitou Mountain in Hua Shixia Valley is modeled, and the critical heights of embankment are figured out by computers , respectively for asphalt-paved, concrete and gravel road surface, according to the natural geographic and geologic conditions of Hua Shixia Valley along the National Road 214. The modeled results are in good agreement with the field data on the Qinghai-Xizang Highway.
