| Abstract: | Subgrade with insulation layer, as the engineering measure for regulating stability of subgrade in frozen soil region, has been applied in permafrost region in Qinghai-Tibet Plateau. In order to perfect the design and improve the construction and quality control of this measure, the issues need to be paid attention to during application of subgrade with insulation layer are pointed out, which is carried out on the basis of the summary of research achievements on permafrost in Qinghai-Tibet Highway and in combination with the practices in the design and construction of ＂Gonghe-Yushu Highway Project＂. |
