摘要
阐述了连续刚构桥是大跨径梁桥发展的必然趋势 ,以及要解决的防止过大温度应力及防止船撞的措施 ;收集和分析了国内外大跨径连续刚构桥的数据和资料 。
Adopting the structure of continuous rigid frame in construction of large span beam bridge is an inevitable developing trend. The measures for decreasing temperature stress and protecting piers from vessel impacting are described. The data from some of domestic and overseas large span beam bridges with continuous rigid frame structure are given and analyzed. The superstruture lightening and non drop construction for closing up of side span are discussed in the paper.
