摘要
结合西南岩溶地区某高速公路一已建岩溶隧道,利用有限差分软件FLAC3D分别对侧部分布溶洞或落水洞的隧道围岩稳定性进行数值模拟研究,通过研究岩溶隧道掘进中围岩变形和破坏的规律,以提前做好各种预防措施,可为岩溶地区同类隧道工程的设计、施工提供参考。
In this paper, a karst tunnel of a highway in the karst area of southwest China that has been built was studied. FLAC3D software was used to simulate the stability of the tunnel surrounding rock, which is covered with caves or sink holes at the lateral. In order to prepare preventive measures in advance, the deformation and destruction rules in the excavation process of tunnel surrounding rock were discussed, which could provide the reference for tile design and construction of similar tunnel engineering in karst regions.
