根据坝式路堤设计的库容特性,考虑库区蓄水、存水损失、泄洪需要,运用蓄水增量法,对坝式路堤涵洞及附属泄洪设施设计进行了水文分析,给出了坝式路堤涵洞及附属泄洪设施免建、缓建或与坝式路堤同期建设方案的确定方法,得到了坝式路堤具有蓄水坝功能的年限计算方法。结果表明:该方法对干旱、半干旱地区坝式路堤涵洞及附属泄洪设施的设计具有参考价值。
According to the reservoir capacity of dam embankment design, the hydrological analysis of embankment culvert and its associated flood discharge facilities was carried out by considering the reservoir water storage, water loss and flood discharge requirements. The dam embankment Culverts and ancillary flood discharge facilities exempt from construction, slow construction or construction of dam embankment over the same period to determine the method to obtain dam embankment has the function of dam years calculation. The results show that this method has reference value for the design of dam embankment culvert and its associated flood discharge facilities in arid and semiarid regions.
