摘要根据换乘要求，成都地铁8号线倪家桥站在既有1号线车站下方设置密贴下穿的换乘通道。以此工程为依托，采用现场测试和数值模拟方法，对地铁列车振动荷载下密贴下穿通道的动力响应特征进行研究，并对比分析下穿通道顶板厚度、侧墙厚度和中墙厚度等因素对上述动力响应的影响规律。研究结果表明：在时域上，随着下穿通道顶板与既有车站底板(两者密贴)厚度比RRF或下穿通道中墙与侧墙厚度比RMS增大，下穿通道总体振动响应均减弱，但减弱幅度逐渐降低；从这个角度得出最优RRF和RMS分别建议为1.5和1.0。下穿通道各部位振动响应强度(加速度幅值，不考虑方向性)沿竖向由上至下、沿横向由中间向两侧衰减，具体为：顶板＞中墙＞侧墙＞底板。在频域上，下穿通道振动频响范围为40～160 Hz，RRF和RMS的增加不改变结构频响范围的分布，但对振动强度，尤其是高频振动强度有明显抑制作用。

Abstract：According to the transfer requirements，a transfer underpass of the Nijiaqiao Station of Chengdu Metro Line 8 is constructed under the existing station of Line 1 with zero clearance. Based on the project，the dynamic responses of the underlying transfer underpass under the influence of trains? dynamic loads from the existing metro station are compared and analyzed by in-situ tests and numerical simulation methods. The effects of the following three factors on the dynamic responses have been investigated，including ceiling thickness，sidewall thickness，and middle wall thickness. The results show that in the time domain，the overall dynamic responses of the closely underlying underpass tend to attenuate with the thickness ratio of the underpass ceiling to the existing metro station floor slab(RRF) or the thickness ratio of the middle wall to the side wall of the underpass(RMS)，but the attenuation rate decreases with the RRF or RMS. From this view，the RRF and RMS are recommended to adopt 1.5 and 1.0 as the optimized values，respectively. The dynamic response magnitudes (i.e.，acceleration peak values，ignoring their directions) of the underpass decreases spatially from top to bottom and from the middle to the sides，i.e.，ceiling＞middle wall＞sidewall＞floor slab. The frequency domain shows that the underpass has a dynamic frequency response ranging from 40‐160 Hz. The increase of RRF and RMS have no influences on the frequency response distribution but have appreciable suppression effects on the dynamic magnitude，especially high-frequency dynamic magnitude.
