摘　　要：在实践调研资料分析的基础上,选取合适的路基震动加速度,就某地一高架桥下穿公路路基的震动作用对该桥的影响进行了数值模拟分析,结果表明,按照下穿路基设计标准,该下穿路对桥梁的影响较小。Based on the practice investigation and data analysis, selecting the suitable sub-grade vibration acceleration, this paper made numeri- cal simulation analysis on the influence of the vibration effect of a viaduct underpass highway sub-grade to the bridge, the results showed that, ac- cording to the design standard of underpass sub-grade, had little influence to underpass bridge.
