| 高速列車振動引發(fā)地層位移響應分析(51 卷) |
| 英文標題 |
| Response analysis of ground displacement induced by vibration of high-speed train |
| 摘要 |
| 通過FLAC3D軟件對列車荷載引發(fā)的盾構隧道動力響應進行了數(shù)值模擬，分析了列車高速通過隧道時盾構管片以及地層的位移變化規(guī)律。結果表明，單列列車經(jīng)過左側隧道時，豎向位移分布呈不對稱狀態(tài)，兩列列車交會經(jīng)過時，位移等值線基本呈對稱分布，地表位移峰值出現(xiàn)在兩隧道軸線附 |
