摘要
当桥梁位于高等级公路的弯道上 ,曲线半径较大 ,而桥梁跨径较小时 ,可“以直代弯”修建成直桥。从力学特性方面分析弯桥直作的可行性。该方法可简化计算 。
When the bridge is located in The high grade highway,the radius of the curve is large,and the span of the bridge is short. Most of this bridges can be built as curved bridges composed of straight girders. This paper analyzes the reliability of the curved bridges composed of straight girders from character of static dynamics. This method can simplify the calculation,and lower the construction cost and construction difficulty.
