Mike11一维水动力模型在桥梁壅水计算中的应用

1D hydrodynamic model of Mike11 on the calculator of bridge backwater

针对新建桥梁壅水的特点,采用Mike11一维水动力模型计算了一典型河流桥梁修建前后水位壅高值,并且与经验公式计算值和Hec-Ras模型计算值进行了比较。水位壅高相差不大,壅水影响长度相差略大,故仍需进一步探索研究。

For the features of new bridge backwater, ID hydrodynamic model of Milell is used to compare the typical values backwaters for building bridge. It is compared the value of Mikell with empirical formula and Hec-Rad model. The values of backwater are similar, but the impact lengths of backwater are different in every model.
