摘要
本文分析了南昆线纳赖峰洼地区柑子坪、红布井、白毡帽、花底湾、下坡岗５条暗河的纵剖面地质物点及其对隧道群方案比选的影响，从而确定了隧道设计的最优方案。
in the Na-Lai mountainous and depressed regions of the Nanning-Kunndng Railway Line,there are five underground rivers at Ganziping, Hongbujing, Baizhanmao, Huadiwanand Xiapogang respectively. Along the longitudinal cross-sectins of these rivers, the geological specialities are analyzed,its influences on the comparison and selection of a set of tunnelsare discussed,and thus the optimum schemes of tunnel design have been determined.
