形态勘测法在中小型河流桥梁设计中的应用

Application of Pattern Surveying in Small and Medium Sized River Bridge Design

结合蒙西铁路沿线中小型河流勘测实例,利用形态勘测法推算出设计流量;介绍了形态勘测法的适用条件、工作步骤、历史洪水调查、勘察测量及计算分析等内容;并用面积比拟法进行验证,证明了形态勘测法在中小型河流桥梁设计中具有精度高的特点。

combined with the small and medium sized river surveying instances along Mengxi Railway, pattern surveying method is used to calculate the design flow, and the application conditions for pattern surveying method, work procedures, historical flood survey, survey measurement, calculation and analysis, etc are introduced. In addition, it is verified by area comparison method that pattern surveying method has shown high accuracy in small and medium sized river bridge design.
