| 摘 要： | 本文基于结构可靠性理论，对铁路桥梁设计规范的校准进行了探讨.从满足可靠度推
算出发，选定出合理的列车活载概率模型。对常用铁路桥梁的既有可靠指标进行了推
算。按所校准范围和一简化的验算式，初步选择出分项安全系数。

| Abstract: | Based on the theory of structural reliability, the calibration for the design code of railway bridges is worked out. A probability model of train loading is rationally selected for the calculation of reliability indexes. Then, reliability indexes of existing typical railway bridges are estimated, and partial safety factors required in the bridge code are suggested. |

| Keywords: | structural reliability railway bridges reliability standard calibration safety factor |
