| 摘 要： | 北方地区每年开春时期基坑土钉支护事故比较多,这与季节冻土的影响有关。公路边坡永久土钉支护的应用越来越多,季节冻土地区需要重视土体冻融对公路土钉支护的影响。这方面的研究工作目前开展很少。本文结合国内外的土钉支护工程实例和国外研究成果,探讨季节冻土对土钉支护的影响机理,以期对土钉支护的设计与施工提供参考和借鉴。

| Abstract: | The accidents of soil nailing for foundation excavation in frost-susceptible areas in early spring are more than in other seasons.The main reason is the influence of the frozen soil.With the increase of retaining structures supported by soil nailing in highway engineering,more attention should be paid to the influence of frost-thaw cycle on soil nailing.However,there has been little research on soil nailing in frost-susceptible environment.In this paper,some examples of soil nailing monitored in winter are introduced and the behaviors of soil nailing under frost conditions are discussed.The results indicate that frost may have significant influence on soil nailing. |
