| Summary: | In order to provide the technical support for the Qinghai-Tibet Highway bridge design, a field survey was carried out. The survey started from Golmud and ended in Lhasa, which was a 1183 kilometers route. A comprehensive analysis was made on the aspects of bridge type selection, scheme design, bridge deterioration etc. Typical deteriorations such as pier crack, bridge transition segment un-uniform settlement were found. Considering the specific situation of Qinghai-Tibet Highway bridge design, practical solutions were proposed on these governing issues: pile design and configuration in permafrost region, superstructure selection, bridge transition segment design. |
