上游水库对于铁路桥梁桥址处流量影响的研究

Study on the influence of upstream reservoir on the flow of railway bridges

铁路桥梁勘测设计是铁路桥梁设计的重要基础和依据。在外业勘测阶段,详细调查沿线水库情况,并针对不同水库特性和位置关系计算河流流量,确定桥涵孔跨,是外业工作中桥梁专业的重要工作内容。以某高铁项目初测为例,研究了上游水库对于桥址处流量影响的几种思路,对于桥梁选址和选型具有重要的参考意义。

Railway bridge survey is an important basis for railway bridge design.In the stage of field investigation,it is an important task for bridge specialty group to investigate the reservoir along the line in detail,calculate the river flow according to the characteristics and location relationship of different reservoirs,and determine the span of bridge culvert.Taking the preliminary survey of a high-speed railway project as an example,this paper studies several ways of thinking about the influence of upstream reservoir on bridge site flow,which has important reference significance for bridge site selection and selection.
