In this paper,described the basic concepts of reliability for construction and structure,determined the basic method of JC method for reliability analysis of bridge construction,to take reliability evaluation of prefabricated simply support beam bridge as an example,and given the specific methods and processes.Calculating the construction reliability indicator through Matlab software and analyzing the parameter sensitivity,so it directs the construction control.%阐述了施工可靠度和结构可靠度的基本概念,确定了JC法用于桥梁施工可靠度分析的基本方法。以装配式简支梁桥可靠性评估为例,给出了具体方法和过程,通过Matlab软件计算施工可靠指标,进行参数敏感性分析,对施工控制有一定指导意义。
