摘　　要：针对公路桥梁大角度斜跨铁路线的特殊情况,介绍了三种跨线架梁施工方案:架桥机架梁、栈桥式吊机架梁和采用斜置门吊加跨线导梁的架梁方案。并对其方案特点进行了分析、比较研究,指出各方案的利弊和适用范围,对今后的类似工程有很好的借鉴和参考作用。With the special conditions of erecting beams for highway bridges diagonally crossing railways taken into account,introduced in the paper are three beam-erecting schemes for road bridges diagonally cross- ing the railway at large angles, namely, erecting beams with a beam erector, erecting beams with a jetty-type crane, and erecting beams with a diagonally-positioned gantry crane plus line-crossing guide beams, with the characteristics of all the three con- struction schemes analyzed, compared and studied, and with both merits and demerits, and the range of application of each con- struction scheme pointed out. The paper may serve as a very good rderence for other similar projects in the future.
