铁路不同厚度片石保温护坡降温效果对比分析

Comparison and analysis on railway different thicknesses rubble temperature slope protection cooling effect

指出片石护坡是保护路基及基底下多年冻土的一种有效工程措施,结合青藏铁路清水河试验段片石护坡试验工程的测试数据,对0.8 m,1.2 m两种不同厚度片石护坡的降温效果进行了对比分析,以推广片石保温护坡的应用。

The author points out that the rubble slope protection is a effective construction measure of protecting foundation and permafrost soil under the foundation, combining with the testing data of Qingzang railway Qingshui river testing section＇ s rubble slope protection experimental construction, it author makes comparison and analysis on the cooling effect between two different thicknesses of 0.8 m and 1.2 m rubble slope protection, so as to promote the application of rubble temperature slope protection.
