| Abstract: | After foundation of state, our country increasingly attaches an importance to bridge detection engineering and estimation of bridge for quality reliability. Selection of scientific estimations has a great significancy. In practical detection, the field data of detection are assumed owing to excessive deflection arisen from overload. The paper analyzes estimation of reliability on bridge in response to principles of improved first moment of second order. |
