Abstract For solving engineering geological problem along the Dali-Ruili segment located in western Yunnan of Pan-Asia railway network, and getting through the important strategic channel between China and southeast Asia as soon as possible, the comprehensive geological structure research team finished the 1∶25 000 geological map and engineering geological map covering the Dali-Ruili railway based on the 22 sheets 1∶50 000 geological maps from regional geological surveying work along the railway. From a multidisciplinary perspective,the team systematically identified and evaluated the basic geological and engineering geological conditions of the railway construction, the type and distribution of geological disaster, the activity of the main fault zones and their effects on railway engineering and the engineering stability of the Gaoligong Mountains section, etc.. The excellent geological work provides an important support and geological safe guard to the route selection, design and construction of the Dali-Ruili railway, and is helpful to reduce the blindness of railway engineering design and construction in the future. This work created a new mode on the combining basic geological survey and major engineering construction in China, and was known as a typical example on the basic geological work in the service of the national major projects construction.
