摘    要:该文针对多线斜交桥渡在斜交角度较大的情况下,目前尚缺少理论及经验计算方法的特点,对某多线大角度斜交桥渡进行了水工模型试验。通过模型试验表明:在相同孔跨条件下,雍水值随斜交角的变化比较平缓,设计方案是可行的。实践证明顺水流方向布置桥墩是解决多线斜交桥墩台阻水问题的有效途径之一。

关 键 词:斜交桥渡  多线桥  雍水  模型试验  工程实践

Abstract:The paper makes hydro-technological model test for a certain skew transporter bridge with multi line large angle, to counter the condition of multi-line skew transporter bridge with larger skew angle and the characteristics now of calculation method that is lack of theory and experience. Through model test it is shown that in the condition of the same span the value of hammed water is gentler with the change of skew angle. So the design option is feasible. The practice proves that to arrange bridge pier in the direction along flow is one of effect way for solving water stop problem of multi line skew bridge abutment pier.
Keywords:skew transporter bridge   multi-line bridge   hammed water   test for model   engineering practice
