| 摘 要： | 本文根据型梁的抗剪试验结果及有关国内外抗剪试验数据的统计分析，并结合各个协作单位所提供的桥梁主要荷载，材料强度及几何尺寸资料，应用可靠性理论的分位值法地标准设计钢筋混凝土及预应力混凝土铁路简支梁几种跨度的笠截面抗剪度可靠指标进行了计算。分析结果表明：斜截面抗剪经度经验公式的不同，对可靠指标有定影响，但只要所建议的经验公式足够精确，这种影响是可以得到控制的。

| Abstract: | Based on model test collecting test data of shear strength at home and abroad and statistical results of traffic load , material strength and body dimension, the rellabllity index of diadond shear strength of railway RC and PC Standard simple beams is calculated by Rackwitz- Fiessler Rdiability Method.It iS found that different claculating formula of shear strength has an effect upon reliability index but the effect can be controlled provided that the accuracy of the recommanded formula is adequate. |
