摘要(Abstract):
为梳理总结极端冰雪灾害对边坡工程极限状态的影响,以2008年南方地区极端冰雪灾害为研究背景,探讨10年来极端冰雪灾害条件下边坡工程的研究进展。因此,本文从资料分析入手,对极端冰雪灾害条件下边坡工程进行了研究。首先,研究了极端冰雪灾害的概念并归纳总结了现行工程规范对极端冰雪灾害条件下边坡工程的相关规定;其次,总结了国内极端冰雪灾害条件对边坡工程稳定性影响的研究现状并进行了述评;再次,对极限状态设计方法的合理性及其研究现状进行了总结;最后,对可靠度理论、工程设计基准期、荷载分项系数的研究现状进行了总结概括,进一步明确了极端冰雪灾害条件对边坡工程影响的下一步研究内容。研究所得成果为极端冰雪灾害条件下边坡工程的设计、施工提供了经验理论,具有参考价值。
