| 地鐵隧道不同軌道結(jié)構(gòu)形式對建筑物減振的仿真分析(51 卷) |
| 英文標題 |
| Simulation analysis on influence of different track types in metro tunnel on vibration-reducing of structure |
| 摘要 |
| 建立隧道—土層—某建筑物的二維有限元模型，分別施加整體道床和鋼彈簧浮置板道床區(qū)段的實測邊墻豎向加速度，計算出不同軌道結(jié)構(gòu)形式下建筑物的振動響應。計算結(jié)果表明，埋深相同時鋼彈簧浮置板道床相對于整體道床可使鄰近建筑物豎向振動加速度減小約80%；采用整體道床時鄰近 |
