摘　　要：针对目前土钉支护设计中安全系数不能真实反映土钉支护的安全性的问题,提出了土钉支护整体稳定概率分析的方法,并编制了计算程序。通过算例证明了本文方法与基于确定性分析法得到的土钉支护的安全系数相同,由于土钉参数的变异性不同,实际的破坏概率可能相差巨大．应尽快将安全系数设计法改进为概率分析法．Because of the safety factor based on current analysis methods can not reflect the real safety of a slope, this paper proposed a new method-reliability analysis method, and made a calculation program. Through cases analysis, it has been shown that through the salty factor are the same, but the reliability are different. The authors suggested that salty factor methods should be replaced by reliability method proposed in this paper.
