Owing to located at the backwater effect end of 315 to water level of Sanmenxia reservior, the Dayudu area in the Yellow River was cause dammed water in the middle of January of 1996 when cold air overcasted with temperature falling down 5 to 7℃, which brought about ice accumulation in channel and ice blocking the river under discharge of around 300m3/s.

长时间的低温风雪天气，以及大风降温初期在黄河小北干流和潼关河段所形成的冰凌堆积，又直接导致冰塞壅水节节上延。

This paper taking the ShunBi river bridge backwater computation as an example,introduced the basic approaches,the main steps and the attentions in bridge backwater computation when using Hec-Ras software.

以大理至瑞丽铁路顺濞河大桥壅水计算为例,介绍Hec-Ras软件计算桥梁壅水的基本方法、主要步骤及注意事项,Hec-Ras软件界面简洁,操作方便,计算效率较高,值得推广应用,其计算结果与《铁路工程水文勘测设计规范》计算结果相比,雍水高度相差不大,雍水长度相差略大,故仍需进一步探索研究。
