摘　　要：在推动西北地区经济发展过程中,高速铁路起到的作用至关重要。但是,因为环境、气候等因素的影响,西北地区大部分都属于季节性冻土区,高速铁路路基冻害问题相对严重,对高速铁路路基安全产生了较大的影响,高速铁路列车在行驶时,难以达到提速要求,导致高速铁路未能发挥应有的作用,对西北地区经济发展产生了一定的影响。因此加强高速铁路路基冻害特征分析,采用科学合理的方式,提高路基的稳定性势在必行。基于此,本文对西北地区季节性冻土区某高速铁路冻土区路基冻害主要类型、原因以及相应的解决措施进行了探讨。In the process of promoting the economic development of Northwest China,high-speed railway plays a very important role.However,because of the influence of environment,climate and other factors,most of the northwest region belongs to the seasonal permafrost area,the problem of high-speed railway subgrade frost damage is relatively serious,which has a great impact on the safety of high-speed railway subgrade,and it is difficult to meet the speed increase requirements when the high-speed railway train is running,resulting in the failure of high-speed railway to play its due role,which has a certain impact on the economic development of Northwest China.Therefore,it is imperative to strengthen the analysis of the freezing damage characteristics of the high-speed railway subgrade and adopt a scientific and reasonable way to improve the stability of the subgrade.Based on this,this paper discusses the main types,causes and corresponding solutions of subgrade frost damage in a high-speed railway permafrost area in the seasonal permafrost area of Northwest China.
