　　Lanzhou-Chongqing Railway is the most complicated railway in mountainous area. It is very difficult to construct and the risk is very high. The section No.5 of civil engineering project of Lanzhou-Chongqing Railway undertaken by CCCC Second Highway Engineering Co., Ltd. is located in Longnan of Gansu Province. The length of the railway is 33.45 km and the ratio of bridge and tunnel is 83%. The large deformation of soft rock with high in-situ stress encountered in the construction of Liangshui Tunnel is regarded as a rare problem in China and the world by experts. There are 3305 trusses in Wudu girder fabrication yard, which is the largest beam yard in the whole line. Longnan station has become a new landmark in Longnan.
