摘　　要：在现行规范理论与结构可靠度理论基础上,建立在役桥梁结构状态安全性综合评估模型,通过现场对桥梁进行调查与检测,确定综合评估模型中各计算公式的时变技术参数,对在役桥梁进行了计算分析与评估.结果表明,该方法的评估结论与桥梁检测和可靠度分析的结果相吻合,能够比较有效地反映出桥梁的实际使用情况.This paper establishes a comprehensive structural safety evaluation model of existing bridges based on the theories of current codes and structural reliability. Through the field investigation and detection, we determine the time-varying technical parameters of each calculation formula in the comprehensive evaluation model, and then analyze and evaluate the existing bridges. The results show that the evaluation conclusions are consistent with the results of bridge detection and reliability analysis, and they can effectively reflect the actual use of the bridges.
