摘要
针对黄河三角洲粉砂壤土盐碱地特点,以山东省小开河引黄灌区为研究对象,对研究区暗管适宜埋深范围及考虑蒸发影响下的暗管铺设适宜间距进行了探讨,并考虑工程建设、材料及不同埋深及间距组合的成本差异,以单位面积投资最小为目标建立黄河三角洲盐碱地工程治理暗管布设系统优化模型,对暗管埋深与间距的最佳组合进行了研究。结果表明,暗管埋深2.4m、间距137.0m为最优方案。结果可为综合考虑经济性、治碱效果及技术操作性的黄河三角洲盐碱地综合治理适宜工程布置形式提供理论依据。
In view of sandy loam saline land in the Yellow River Delta district, taking Xiaokaihe Huanghe water diverting irrigation district of Shandong Province for research object, this paper discusses appropriate buried depth range and arrangement span of underground pipe considering the effect of evaporation. Considering the cost difference of project construction, material, different buried depth and combination span, underground drainage pipe system optimization model of saline land 〖JP〗harnessing is established by taking unit area minimal investment as target. Finally, the optimal underground pipe combination of buried depth and span are analyzed. The results show that underground pipe combination of 2.4 m buried depth and 137.0 m span is the best scheme. The results can provide theoretical basis for project arrangement of saline land harnessing in the Yellow River Delta District in consideration of economy, solodization effect and technical operation.
