Research on Construction Technology of Seasonal Frozen Ground Subgrade in High Altitude Area
The problem of seasonal frozen ground in Gannan Tibetan area has caused great difficulty in the construction of subgrade in highway engineering.In order to realize the quality construction of road engineering,scientifically select construction technical measures,ensure road quality engineering and provide technical support for the realization of project functional objectives,this paper mainly focuses on the freezing damage of highway subgrade in the seasonal frozen ground region of Northwest China,provides specific engineering technical measures by studying the treatment methods of seasonal frozen ground distribution in the process of project construction management,summarizes and analyzes the key technical problems of road engineering construction,and provides the experience of road engineering construction in other alpine and high altitude areas of Northwest China.
