研究了多年冻土区主动保护多年冻土的新型路基结构形式——粒径改良路基。粒径改良路基对降低路基下填土地温具有良好的工程效果,与普通通风路基、普通路基相比,在保护冻土方面已显现出较好的优越性。
This paper studies the new subgrade structure form - particle size improvement subgrade that takes the initiative to protect permafrost in permafrost regions. The improved particle size roadbed has a good engineering effect to reduce the ground temperature under the embankment. Compared with ordinary ventilation subgrade and ordinary subgrade, the improvement of particle size has shown a good advantage in the protection of frozen soil.
