摘要
椒江二桥位于浙江省台州市椒江入海口处,是一座重要的公路兼城市桥梁。根据当地的建设条件对桥位、跨径和桥型进行了综合比选,最终确定主桥为跨度(70+140+480+140+70)m的双塔双索面斜拉桥方案。主塔采用钻石形,主梁横断面为独创的半封闭钢箱组合梁,该桥建成后必将成为台州市新的景观亮点。
The Second Jiaojiang Bridge is an important highway and city bridge located at the estuary of Jiaojiang River in Taizhou City of Zhejiang Province. According to the local construction conditions, the bridge location,span,and bridge style are compared,and the final plan of 2 towers and double-cable-plane cable-stayed bridge with the span of（70＋140＋480＋140＋70） m is determined. The towers adopt the diamond style,the main beams adopt the originative semi-closed steel box composite girder. This bridge will be a new bright spot of Taizhou City.
