摘　　要：鉴于安全系数取值对滑坡防治工程的成效和费用有很大的影响,由安全系数定义的安全储备系数能否衡量滑坡在治理后的安全储备值得深思,列出了不同国家和行业的几个标准,来说明和探讨这一问题,结论指出安全度分析需同时考虑安全储备系数和治理后的稳定系数,并推举出抗滑支挡设计荷载的取值建议方法。Based on choosing safety factor that has prodigious influence on effect and expense of prevention and cure in the landslide, whether safety repertory factor of landslide defined according to safety factor can weigh landslide safety repertory value behind being fathered or not is worth pondering over. Several criterions of different country and industry are listed in order to explain and discuss this problem. The conclusion indicates that safety degree analyse need consider safety repertory factor and stable factor behind being fathering,and put forward choosing value advice method of loads in the design of anti-sliding and supporting and holding up.

关 键 词：安全储备 安全系数 稳定系数 安全等级
