孤山河及桥梁壅水计算分析

Calculation and analysis of the design flow and Gushan River Bridge backwater

孤山河为海城河上游,没有实测洪水资料,采用海城站水文资料,使用面积比拟法对孤山河桥断面进行洪水计算,同时,对孤山桥断面的壅水高度及长度进行计算,并对计算结果进行了分析。

Gushan River is the upstream of Haicheng River, there is no measured data of flood, so using the Haicheng station hydrological data. This paper uses the area analogue method to compute the flood calculation of the bridge crossing section of Gushan River, and the length and height of the backwater, analysis of the calculation result.
