高寒和多年冻土地区路桥施工技术

Road&Bridge Construction Technology in Alpine and Permafrost Regions

由于冻土地区常年受到高寒季节的冻融影响,导致物理地质和工程地质出现各种不良现象,有些还破坏了土体原有的平衡,加上冻土地区受热力学平衡的影响,严重破坏了公路路基和建筑物。

Owing to the perennial frozen soil area affected by alpine seasonal freezing and thawing, lead to all kinds of bad physical geology and engineering geology phenomenon, some also destroyed the balance of soil, and permafrost region is influenced by thermodynamic equilibrium, serious damage to the highway subgrade and buildings.
