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.
