Geological Line Selection for the Qinghai-Tibet Railway Engineering

Mr. Jin-Cheng Li, Vice President of China Railway First Survey & Design Institute Group, has been working as the Chief Engineer on the Qinghai-Tibetan railway construction project since 2000 and has accumulated substantial first-hand experience of railway routing in complicated geological environment on Qinghai-Tibetan plateau, such as railway routing in permafrost regions, active fault zones, meizoseismal areas, natural reserves, slope-geohazard regions, as well as geothermal, windy-sand, and snow drift hazard regions. He has several important publications to his name and has won a number of honors for his outstanding contributions to the construction of more than ten national key railway projects.
