| 摘 要： | 利用水力水文计算基本原理,研究了竖曲线内桥面泄水孔间距。根据桥面街沟允许水面宽度和允许水流流量,用试算法逐段确定泄水孔间距,并指出影响泄水孔间距的主要因素是泄水孔截流率。通过研究和算例说明竖曲线桥面泄水孔布设是不均匀的,工程中应根据桥面几何参数和当地气候条件计算泄水孔间距。

| Abstract: | This paper studied the design of scupper spacing of deck in vertical curve with the basic principle of hydraulic and hydrologic compute.According to the permitting width and the permitting flow capacity of the street gutter on deck,the spacing of deck can be obtained one section after one section by trail method.It is pointed that, the scupper spacing of deck in vertical curve, which is related to the rate of flow from weep hole,is not equal according to the study and an example. The results indicate that the scupper spacing should be computed according to the geometry parameters of deck and the local climate conditions. |
