摘　　要：近年来,季节性冻土区公路路基冻害研究已取得了长足的进步,但是,因受气候、环境、冻融循环等不同因素的影响,季节性冻土区公路路基冻害问题依然突出.随着国家公路规划网的逐步实施,将有更多的公路工程向季节性冻土区推进,为了将已有的研究成果更好地应用于工程实践,需对其进行综合评述.基于前期的研究基础,总结我国季节性冻土区公路路基冻害的主要破坏形式及分布区域,讨论影响路基冻害的几个主要因素,分析和总结已有公路路基冻害防治措施的研究现状,提出季节性冻土区公路工程面临的问题和研究建议,为深化季节性冻土区公路路基冻害及其防治研究提供新思路.Roadbed is significantly affected by the climate,environment and freezing-thawing cycles,thus frozen damage is still a serious problem in the roadbed construction in seasonal frozen ground regions,though many advances in the frozen damage researches have been achieved. With the road projects developing in China,more and more roads will be built in the seasonally frozen ground regions. So as to guide engineering practice better,it is necessary to make a newdocument reviewon the research findings in this field. Based on the previous studies,the distribution areas and the major failure forms of roadbed frozen damage are summarized; the main influencing factors that cause engineering problems to the roadbed are discussed; the existing counter measures are analyzed and summarized in this paper. Meantime,some ongoing engineering problems and suggestions are put forward,which provide newideas for improving the studies on roadbed frozen damage and counter measures in seasonal frozen ground regions.
