笔者接触到桥梁溃坝水文计算,应用《公路桥位勘测设计规程》(以下简称《桥位规》)时发现若干问题,商榷于后,供交流参考。一、桥位处的溃坝流量《桥位规》7.4.2条中,位于非永久性水库内的桥梁,应按溃坝情况验算。溃坝后库内桥梁的桥下流量按图-1所示的图式计算 The author came into contact with the dam break hydrology calculation, the application of “Highway Bridge Survey Design Code” (hereinafter referred to as “bridge gauge”) found a number of issues, after discussion, for the exchange of reference. First, the bridge at the dam break flow “Bridge gauge” Article 7.4.2, is located in the non-permanent reservoir of the bridge should be checked dam failure situation. After the dam break the bridge under the bridge traffic flow chart shown in Figure -1 calculation
