Qinghai-Tibet Railway Project passes acceptance check
The acceptance check of a major CAS project on Qinghai-Tibet Railway construction has recently been completed by the national evaluation team in Lanzhou, Gansu Province.
Entitled The Construction of the Qinghai-Tibet Railway and Its Engineering/ Environmental Impacts on the Permafrost Ground, the project, composing of seven subcomponents, was considered to have well reached the preset research goals with good organization and management, and rational outlay. Experts said that the original research breakthroughs in conquering permafrost areas were the essentials to the success of the entire program.
Initiated by CAS in 2001 just before the start-up of Qinghai-Tibet Railway construction, the project was aimed at solving three worldwide difficulties facing such construction, including permafrost earth, high altitude conditions and environmental protection on the plateau. Under the organization of the CAS Cold and Arid Area Environment and Engineering Research Institute, the team was made up of more than 120 scientists from 15 research bodies across China. Base on the experience of building the Qinghai-Tibet Highway and Qinghai-Kangding Highway, the team proposed a crucial technological innovation of 'automatically cool down the rail bed' instead of simply maintaining its temperature. The idea was later proved to be the key breakthrough in solving the permafrost handicap.
The projects have received a number of prizes and rewards over the past five years, for instance the Advanced Research Group Reward by CAS and the Ministry of Personnel in 2002, the Innovative Workgroup of CAS in 2003, and the CAS Outstanding S&T Achievements Award in 2005.
