摘要

通过大型振动台模型试验研究了减震层效能评定方法的准确性和减震层作用下衬砌结构与最不利的IV级和V级围岩在激振过程中的相互作用。研究结果表明：减震层效能评定方法可以较为准确地评估减震层在地震动力作用下对衬砌结构的作用效果，但随着激振加速度峰值的提高，试验值会与评估值产生偏差，因此对减震层效能评定方法引入地震动力损伤系数以提高其精确度；围岩级别相较于减震层的厚度对衬砌结构的地震响应更具有决定性作用；在中低烈度地震区，减震层对衬砌结构的保护效果较为明显，但减震层存在最优厚度，超过该厚度，衬砌结构遭遇地震时的震动更加强烈，在高烈度地震区，减震层的效果差异在不同围岩中逐渐不再明显；减震层的存在改变了衬砌结构的自振特性，让衬砌与围岩之间在地震动力作用下有一定的刚性位移裕度，减少了相对位移的幅值。

Abstract

Using shaking table model tests, the accuracy of the evaluation method for damping layer and the interaction between the lining structure and grade IV as well grade V surrounding rock with seismic excitation were researched, which were the most adverse surrounding rock condition. The results show that: the evaluation method can accurately assess the seismic effect of damping layer acting on lining structure, but the test value will deviate from the evaluation value with the increase of peak excitation acceleration. Therefore, a seismic reduction coefficient is introduced to improve the precision of the evaluation method. Further, the grade of surrounding rock plays a more decisive role than the thickness of the damping layer in the seismic response of the lining structure. Besides, in the medium and low-intensity earthquake zones, the protective effect of the damping layer is obvious, but the damping layer has an optimal thickness, beyond which the vibration of the lining structure will be more acute. In terms of the high-intensity earthquake zones, the difference in the protective effect of damping layer is no longer obvious. In addition, damping layer changes the vibration characteristic of lining structure, it creates a rigid displacement margin between the lining structure and surrounding rock, which can reduce the maximum relative displacement with seismic excitation.
