摘 要:在没有河谷水文监测资料的情况下,利用洪丰期水量和引洪流量及河谷断面水文参数,计算出引洪前后鱼简河断面水位、流量的变化,并与河岸农田、村舍等地物分布高程对比,进而评估引洪产生的受灾情况。结果表明在阳朗坝排洪412 m3/s的条件下,鱼简河A-A、C-C地段河谷断面承载流量分别为491.091及476.219m3/s,相对安全,而B-B、D-D地段,河谷断面承载流量分别为365.002及160.675m3/s,将有可能被洪水淹没成灾。Without any hydrologic monitoring data,this paper calculate the water levels and discharges before and after releasing the flood water,in light of the flow data in high water period and the flood releasing flow data as well as river valley section parameter,and evaluate the disaster possibility led by flood releasing,by comparing the calculated results with the height of farmland and cottage along the riverbank.The result proves that the section bearing capacity is 491.091m3/s and 476.219m3/s on section A-A and C-C respectively,which is comparatively safe under the condition of releasing 412m3/s in flow;but the section bearing capacity is 365.002m3/s and 160.675 9m3/s on section B-B and D-D,which will possibly lead to flood disaster under that situation.
