摘要
在通航河流,尤其是在桥区地形、水流条件复杂河段处进行桥梁建设前,必须对河床演变、桥位、净空尺度、通航条件和安全保障等因素进行论证。结合相关规范,提出了确定桥梁通航论证的方法。
Before the construction of bridge over navigable rivers, esp. on the reach of complicated topographical and flow conditions, factors such as bed evolution, bridge site＇s choice, clearance dimensions, navigation condition and safety-ensuring measures, etc. shall be studied. According to related standards, this paper puts forward the studying principle and method for navigation conditions of bridges.
