摘要
复杂溶洞隧道在施工中常遭遇涌水、流沙、突泥、坍塌、隧道变形等地质灾害风险。以贵南高铁九万大山3号复杂溶洞隧道为背景,对于水害,遵循“引、堵、越、绕”方针进行科学防治;针对溶洞处在隧道拱顶、边墙和隧底等不同位置对隧道结构的不同影响,按照溶洞与隧道有无联通采取不同的处置技术。通过监测分析,证明针对复杂溶洞隧道群采取的各种处置技术科学可行。
In the construction of complex karst tunnel,geological hazards such as water gushing,quicksand,mud inrush,collapse and tunnel deformation are often encountered.Against the background of No.3 Complex Karst Cave Tunnel in Jiuwandashan of Guiyang-Nanning High Speed Railway,scientific prevention and control measures are taken according to the policies of“diversion,blocking,crossing and bypassing”;with regard to different impacts on the tunnel structure due to different locations of the karst cave such as at the tunnel vault,side wall and tunnel bottom,different disposal technologies are adopted according to whether the karst cave is connected with the tunnel or not.Through monitoring and analysis,it is proved that various disposal technologies adopted for complex karst tunnel groups are scientific and feasible.
