摘　　要：人为差错是导致桥梁施工期事故的重要原因之一,人为差错对施工期结构的影响主要是通过改变结构设计参数来实现的.在对桥梁结构施工期人为差错的特点、种类分析的基础上,通过研究设计参数对结构施工期可靠度的敏感度来间接反映人为差错对结构施工期可靠性的影响,并结合工程实例进行了应用研究,所得结论对确保桥梁施工安全具有较为重要的指导意义.Human error is one of the most important causes of accidents during bridge construction . Its impact on reliability analysis is achieved by adjusting the design parameters of structures. Based on the analysis of the characteristics and types of human error during this period,the impact of human error on reliability analysis of bridge structure during construction can be reflected indirectly by analysing sensitivity of design parameters. Applied research has been developed for a project. The conclusions in this paper are practical and useful for ensuring the safety of bridge construction.
