Abstract

Relying on the reconstruction project of Naqu to Lhasa highway of National Highway 109, the quality inspection of Dangqu Special Bridge and Cross Qinghai-Tibet Railway Special Bridge, which are two control projects of comparable scale, was carried out by combining appearance inspection and physical inspection methods, which informed the quality condition of the construction of bridges in high-altitude areas of Qinghai-Tibet and elaborated the advantages of the combination of the two quality inspection methods. The quality inspection results show that the quality of Dangqu Special Bridge is obviously better than that of the Cross Qinghai-Tibet Railway Special Bridge, and the two bridges are qualified in the overall inspection, but both of them need to be improved in quality.
