| 摘 要： | 文章以嘎隆拉隧道洞口段为原型,拟定了相似关系,选取了围岩和衬砌的相似材料,制作了公路隧道减震试验模型。在试验模型中设置了减震层,选择了振动台模型试验测点的布置位置,制定了加载制度,进行了振动台加载试验;分析了试验结果,并与有限元分析结果进行了对比,定义了减震率;从应力和应变两方面分析了减震层的动力特性及减震效果,得出减震层的设置对隧道减震能起到一定的作用。 |
| 关 键 词： | 公路隧道 减震层 模型试验 有限元分析 减震率 |

| Abstract: | Using the portal section of the Galongla tunnel as a prototype,model-scale relationships were set up,the analogous materials of surrounding rocks and lining were chosen,and a model for the vibration attenuation test was created.A buffer layer was set around the model.Furthermore,the loading system was established and a loading test on a vibrating platform was carried out.Meanwhile,the test results were analyzed and compared to those of finite-element analysis and vibration attenuation ratios were determined... |
| Keywords: | Highway tunnels Buffer layer Model test Finite-element analysis Vibration attenuation ratio |
