摘要
在公路工程建设中,设计桥梁跨越河流、沟道、灌渠,为保证构造物安全,要采用各种方法进行桥梁设计流量分析计算,以便得到可靠的结果,一般采用实测流量推算、地方经验法、暴雨推理法、形态调查法等.文章结合宁夏特定地区的公路工程,根据不同桥梁的水文、地貌状况,采用特定流量计算方法进行水文流量分析,旨在为桥梁设计提供可靠的水文数据.
Abstract
In the construction of highway engineering,when the bridge is designed to cross rivers,ditches,irrigation canals,in order to ensure the safety of structures,it is necessary to use various methods to analyze and calculate design flow of the bridge,so as to obtain reliable results.Generally,the measured flow calculation,local experience method,rainstorm reasoning method,morphological investigation method and so on are used.Combined with the highway engineering in specific areas of Ningxia,according to the hydrological and geomorphological conditions of different bridges,the hydrological flow analysis is carried out by using the specific flow calculation method,aiming to provide reliable hydrological data for bridge design.
