摘要
桥梁结构风险贯穿于桥梁建设全过程。主要介绍桥梁在方案设计阶段的风险评估方法及其主要评估流程,以实际工程为例,阐述采用专家调查法确定桥梁设计方案的安全风险水平,并采用基于估计相对位置的方案排队法优选出较优方案,为桥梁方案设计阶段的风险评估提供参考依据。
The structural risk of bridges runs consistently through the whole process of bridge construction.This paper mainly introduces risk evaluation methods and principal evaluation processes for bridged at the stage of proposal design,determines levels of safety risk of design proposals by means of expert investigation based on practical projects as examples,and chooses better proposals by queuing method of proposals based on estimation of relative positions.The analysis of the paper provides a reference for risk evaluation of bridges at the stage of proposal design.
