摘要
介绍了铁路连续梁桥在高速列车作用下，冲击系数和列车运行舒适度的研究．计算表明，连续梁桥的冲击系数和列车舒适度，比简支梁桥有一定减小，提出了连续梁桥设计冲击系数．通过对不同跨度配合情况下连续梁桥的动力分析。
The dynamic coefficients of railway continuous bridge under high speed trains and the stability of trains are studied. The study results show that the dynamic coefficients of continuous bridge and train stability are smaller than those of simply supported bridge, and the dynamic coefficients for design are proposed. By analyzing the dynamic responses of continuous bridge when the spans are unequal, the method for calculating dynamic coefficients is discussed.
