| 摘 要： | 岩溶区隧道因受岩溶发育程度的影响,其围岩位移特征与一般隧道存在较大区别。以宜万铁路某岩溶隧道为工程背景,对侧部含有溶洞的隧道施工过程中的围岩位移特征进行了相似模型试验和现场测试。结果表明:隧道开挖后,围岩分别向溶洞内和隧道内变形,溶洞与隧道之间的围岩向两个相反的方向变形,是最危险区域。靠近溶洞附近的边墙、拱肩和拱顶处围岩的位移值要比远离溶洞侧的相应部位处的围岩位移值大。研究结论对岩溶隧道的设计与施工具有一定的参考价值。

| Abstract: | Because of the influence of karst cave,distribution characteristics of displacement of surrounding rock of tunnel in karst zone differs from that of common tunnel.Taking a karst cave tunnel in Yichang-Wanzhou railway as an example,characteristics of displacement of surrounding rock of tunnel with karst cave in it's beside is carried out through physical analogic modeling and field monitoring.Research indicates that after the tunnel is excavated,the surrounding rock is convergented toward the karst cave and ... |
