现如今国内整体地势呈现东低西高的趋势,高原和山地占据59%的国土面积,近年来随着不断发展社会经济和科学技术,国家从重点建设沿海区域,逐渐偏向中西部区域,国家也进一步大力建设偏远区域。高海拔地区具备十分特殊的环境特点,因此填筑路基土方也会出现一定问题,需要进一步研究高海拔路基土方填筑技术。 Nowadays, the overall terrain of the country shows a trend of low east and low west. The plateau and mountainous regions occupy 59% of the land area. In recent years, with the continuous development of social economy and science and technology, the state has gradually shifted from focusing on the coastal areas to the central and western regions. Vigorously build remote areas. High altitude areas have very special environmental characteristics, so there will be some problems filling roadbed earthwork, the need for further research on high-altitude subgrade earthwork filling technology.
