新建安九客运专线大中河流水文分析计算

Hydrological analysis and calculation on large and medium-sized rivers along the newly-constructed Anqing-Jiujiang Passenger Railway Line

新建安九客运专线跨越皖河水系、华阳河水系等长江流域的多条大中河流。文中介绍了大中河流水文计算常用的数理统计法、流域面积比拟法及地方经验公式法,并分别计算了皖水河、潜水河、长河及二郎河的百年一遇流量。通过计算结果及所收集资料的对比分析,最终确定了本线线位处大中河流水文计算的基本思路。

The newly-constructed Anqing-Jiujiang Passenger Railway Line crosses several large and mediumsized rivers of Wan River Drainage and Huayang River Drainage in the Yangtze River valley. In this paper, the frequently used methods in the hydrographic computation, such as Mathematical Statistics Method, Basin Area Analogue Method and Local Empirical Formula Method, are introduced and adopted to calculate the once-in-acentury discharge of Wanshui River, Qianshui River, Chang River and Erlang River. Through comparison of the calculations and data collected, a basic model for the hydrological calculation on large and mediumsized rivers is provided.
