摘要
本文将传统的安全系数视为变量,提出了安全系数的标准差的近似表达式,分析了传统安全系数的可靠度,力求用简单的方式在岩土工程中体现可靠度的理论。在现有计算方法的基础上可方便地获得可靠性指标或失效概率,以利于对工程安全度作出客观的评价,提高判断的正确性。
It regards conventional safety factor as a variable,and offers an approximate formula for its standard de- viation.Reliability of safety factor is estimated.Simple methods are applied to geotechnical engineering to show theory of reliability.It is convenient to acquire reliability index or failure probability according to current calculation methods,and this will add considerable value to the safety analyses of a project.
