| Abstract: | Due to the merits of probabilistic limit state design method which is applied in many fields, in this paper the influencing factors of loads which are treated as random variables on tunnels are analyzed and the recommended values of partial coefficient are presented in order to consider the influence of many uncertain factors and improve the design reliability. |
