中文摘要：

基于动力模型相似理论,设计了一个尺寸为1∶10的偏压隧道模型进行大型振动台试验,研究模型分别在大瑞人工波、Kobe波和汶川波水平竖向双向激振条件下偏压隧道的加速度、动应变和围岩压力的动力响应特性。试验结果表明：偏压隧道竖向加速度响应与地震波、振幅和测点位置有关,且对激振加速度有放大效应,但随输入加速度峰值的增大而减小,受临空坡面放大效应的影响,同一高程靠近坡面的偏压侧放大系数大于非偏压侧（除拱脚外）;水平向加速度响应主要与测点位置关系较大,受波形和振幅影响较小。衬砌在地震作用下主要承受拉应力,主应力随输入加速度峰值的增大而增大,非偏压拱脚主应变值最大是抗震设防的关键部位。

英文摘要：

Based on similar theory of dynamic model, a large-scale shaking table test of unsymmetrically loaded tunnel model with the scale of 1：10 was designed. In order to study seismic response characteristics of acceleration, dynamic strain and surrounding rock pressure of the model, Darui artifical wave, Wenchuan wave and Kobe wave were used to excite the model in X,Z directions. It shows that the vertical acceleration of the tunnel is related to seismic waveform, acceleration amplitude and measuring point＇s location and has an amplification effect on the excited accel-eration, but vertical acceleration amplification coefficients decrease with the increasing earthquake amplitudes. Because of slope, amplification effect, the bias side which is closed to slope, the amplification coefficients is greater than that of unbias side in the same height （ except arch spring）. The horizontal acceleration dynamic response is mainly related to measuring point＇s location and the influence of seismic waveform and amplitude is small. Lining in earthquake bears mainly tensile stress. The primary stress increases with the increasing input of earthquake ampli- tudes. The max and rain principal strain all appear in arch spring of unbias side, so arch spring is the key part of seismic fortification .
