摘要:
季节性冻土地区修建高速铁路的主要工程问题是路基冻胀。针对此问题，近年来铁路建设单位在华北、西北多个高速铁路建设中连续开展了几年的冻胀监测工作。冻胀监测内容多、数据量大，文章综合各线连续几个冻融周期监测成果，对高速铁路路基冻胀评价方法进行了尝试性研究，并总结了冻胀原因，提出了工程措施建议，可为今后类似地区铁路勘察、设计、施工提供参考。
Abstract:
The main engineering problem is the subgrade frost heaving for high-speed railway construction in the seasonal frozen soil area. In response to this problem, in recent years, the railway construction companies have carried out the frost heaving monitoring in construction of multiple high-speed railways in North China and Northwest China for several years. Because of a lot of frost heave monitoring contents and data, this paper, based on the monitoring results of several consecutive freeze-thaw cycles of each line, makes a tentative study on the evaluation method of frost heaving of high-speed railway subgrade, summarizes the causes of frost heaving, and puts forward suggestions for engineering measures, which can provide reference for survey, design and construction of railway in similar areas in the future.
