冻结高度

The heat insulation materials of the XPS of which decrease embankment height, thermal pipes setup in sun-facing side of embankment, crushed rock cover and shading board are used to adjust the subgrade damages caused by the thaw basin. Crushed rock-based embankment and both sides thermal pipes are used to adapted to subgrade damages caused by thaw-sandwich layer. The berms are adapted to subgrade damages caused by the frozen bulge.

针对融化盘偏移所引发的病害，提出可采用XPS板路基降低路基高度，或在阳坡一侧采用热棒路基、碎石护坡路基、遮阳板路基等工程措施进行治理；针对融化夹层所引发的病害，提出可采用片块石路基、双侧热棒路基进行治理；针对冻结核发育所引发的病害，提出可采用防水保温护道进行治理。

The subgrade damages are divided into two-types: high subgrade and low subgrade damages. High subgrade damages of which are related to the embankment height and slope directions maily include longitudinal cracks and subgrade cracks. The higher of the embankment height, the greater of the happening rate. The mechanisms of high subgrade damages formation are analyzed by the observed dates of soil temperature within the embankment and damages survey. In warm permafrost regions, the damages are mainly caused by the formation and development of the thaw bulb and thaw layer. In cold permafrost regions, the damages are mainly caused by frozen bulges.

围绕这些病害特征及形成过程，提出了将多年冻土区填土路基病害分为低路基病害与高路基病害，目前青藏公路路基的病害形式主要表现为以纵向裂缝与路基开裂为主的高路基病害，并提出了高路基病害与路基高度及坡向直接相关，路基高度越高，高路基病害发生的几率越大；通过对高路基地温观测数据的分析，并结合高路基病害的调查结果，研究得出了不同地温区高路基病害的形成机理，提出高温冻土区主要是由于融化盘与融化夹层的形成与发展所引起的，低温冻土区主要是由于冻结核的形成与发展所引起的。
