青海积石峡电站对外公路黄河大桥设计简介

针对连续刚构结构受力特点,对不对称连续刚构桥梁特性进行分析、计算。以青海积石峡电站对外黄河公路大桥为例,验证分析、计算方法的可靠性。通过结构受力计算、整体稳定性,为今后国内设计和修建非对称、特殊荷载的连续刚构桥梁提供一定的设计经验。

Design of Huanghe River Bridge on Highway Linking Outside of Jishi Gorge Power Station in Qinghai

In the light of the characteristics of mechanical behavior of continuous rigidframe structures,the performance of the continuous rigid-frame bridge of asymmetric arrangement is analyzed and calculated,and by way of example of the Huanghe River Bridge on Highway Linking Outside of Jishi Gorge Power Station in Qinghai,the reliability of the analysis and calculation methods as mentioned is verified.The efforts made for the mechanical calculation and global stability analysis of the rigid-frame bridge structure in the paper provide certain experiences for the design and construction of the continuous rigid-frame bridges of asymmetric arrangements and with special loads in China in the future.
