Abstract：Research purposes ： The section between Lanzhou and Guangyuan of Lanzhou - Chongqing Railway Line locates in the southeast part of Gansu Province and the northwest part of Sichuan Province with steep topography, complicated geological structure and unfavorable geological conditions and most of the bridges and tunnels of this railway line will be built in this area. Beichuan, Yingxiu, Qingchuan, Guanxian ( Dujiangyan) and Jiangyou suffered very much from the May 12 Wenchuan Earthquake, separately locate on the Qingchuan Fault ( F8 ) , Beichuan - Yingxiu Fault (F9) and Guangyuan - Jiangyou - Guanxian Fault ( F10) , so it is necessary to do the study on the impact of earthquake on construction of Lanzhou - Chongqing Railway.
Research conclusions ： Based on the site investigation after the earthquake，it is concluded: (1) The earthquake impact on the geological structure and stratum along the railway line is unobvious. (2) The earthquake impact will not produce the large landslide and mudflow in short period of time，but do impact the existing building very much. (3 ) The sequence - disaster caused by the earthquake makes long - term impact，which can possibly cause mudflow. (4) The rock falling caused by the earthquake is very common，which will make impact on the construction of the railway, so the preventive measures should be taken into account in the design and construction stages. In addition, the proposals are made in this paper for the route election, subgrade engineering and bridge and tunnel constructions for construction of the line.
