摘要
随着振兴东北老工业基地和西部大开发战略的实施,季冻区的基础设施建设已经得到很大的发展,但是,季节冻土区边坡的冻融灾害是工程建设中不得不面对的困难之一。到目前为止,季节冻土的理论研究不多且资料很不集中,使得理论研究远远跟不上工程实践的应用要求。因此,季冻区边坡冻融稳定性研究是我们目前面临的主要问题。
本文根据季冻区边坡所处的特殊环境,讨论了季冻区边坡的稳定性影响因素,对季冻区边坡的各种失稳类型有了一个分类。探讨了冻结过程边坡的稳定性,融化过程中边坡的稳定性变化规律和冻融循环对边坡稳定性的影响原因,找到了边坡在冻结过程中最危险的滑动面,然后用该滑动面处的可靠度来进行优化评价。

Abstract
With the revitalization of the old industrial bases in the northeast and the western development strategy, infrastructure seasonal frozen area has been a great development, but disaster seasonal freezing and thawing permafrost zone in the slope of the construction had to face one of the difficulties. So far, the theoretical study of seasonal frozen and the data is very much focused so far behind the theoretical study of engineering practice applications. Therefore, seasonal frozen area thaw stability of the slope is the main problem we are facing.
Based on the slope in seasonal frozen area in which special environment, the stability of the factors discussed in seasonal frozen area of the slope, the various types of unstable slope in seasonal frozen area have a classification. To investigate the stability of the slope of the freezing process, the melting process stability and freeze-thaw cycle variation of the slope of the impact on slope stability reasons, find the slope in the freezing process, the most dangerous sliding surface, and then use the reliability at the sliding surface to optimize the evaluation.
Key words
Freezing and thawing; seasonal frozen slope; stability; reliability
