Abstract：In allusion to the problems of the frozen soil engineering geology, the roadbed stability with climate change, the entironment change and protection in the construction of Qinghai-Tibet Railway, this paper analysed the frozen soil engineering technology problems existed in the construction of Qinghai-Tibet Railway and introduced new ideas and methods for solving these problems: the idea of the actively cooling roadbed and the idea of the dynamic design. Meanwhile, we put forward the problems of considering and research at next phase in the construction of Qinghai-Tibet Railroad.
