摘要

受地形、地质条件及线路走向等因素的限制,隧道近接交叉的净间距越来越小,工程问题越来越复杂。该研究以草莓沟1#和盘道岭立体交叉隧道为例,完成3种激振工况的振动台试验,重点分析受下穿隧道影响,上跨隧道拱顶和仰拱加速度动力响应特征,结果表明:上跨隧道仰拱受相邻隧道波场效应影响,受震有效持续时间更长;受下穿隧道影响,上跨隧道拱顶轴向峰值比表现出更为明显的非线性、非平稳性增大的特点;对隧道结构影响较大卓越主频段集中在2~8 Hz和12~20 Hz,卓越频率取值为5.95 Hz,16.32 Hz;位移卓越频率与加速度响应有差异,宜鼓励提高结构阻尼性能,阻尼比建议值取为20%。研究结果可为立体交叉隧道的抗震设计提供新思路。

Abstract

Due to the limitation of topography, geological conditions and line direction, the net distance between the tunnels near the crossing becomes smaller and smaller, and the engineering problems become more and more complicated.In the paper, a shaking table test under three excitation conditions was carried out by taking Caomeigou 1# and Pandaoling 3D cross tunnels as an example.The acceleration response characteristics of the vault and the invert of the upper span tunnel under the influence of the underpass tunnel were analysed.The results show that: the upper span tunnel invert is affected by the wave field effect of adjacent tunnels, and the effective seismic duration is longer; under the influence of the underpass tunnel, the axial peak ratio of the arch of the upper span tunnel shows more obvious characteristics of non-linearity and non-stationariness; the dominant frequency bands of excellence are concentrated in 2-8 Hz and 12-20 Hz, and the values of excellence frequencies are 5.95 Hz and 16.32 Hz; there is difference between the superior displacement frequency and that on the acceleration response curve, so the damping performance of the structure should be improved.The damping ratio is suggested to be 20%.The research results provide a new idea for the seismic design of three-dimensional cross tunnels.
