摘　　要：根据全国最新“三区三线”划定成果,对原南宁市五化灌区马兰渡槽设计方案进行了变更。通过将原马兰渡槽设计方案与最新“三区三线”划定成果进行比较,提出了原址倒虹吸、原址渡槽两个设计变更方案。随后,从工程占地、地质条件、结构布置、施工运维等方面分析了各设计变更方案的优缺点,综合比选确定原址倒虹吸方案为最优设计方案。The original design scheme of Malan aqueduct in Wuhua Irrigation Zone of Nanning City has been changed based on the latest national regulations on"Three Districts and Three Lines".By comparing the original design scheme of Malan aqueduct with the latest delineation results of"Three Districts and Three Lines",two new design schemes of the original site inverted siphon and the original site aqueduct have been proposed.The advantages and disadvantages of two new design schemes were analyzed from the aspects of engineering land occupation,geological conditions,structural layout,construction and operation maintenance.The original site inverted siphon scheme was determined as the optimal design scheme through comprehensive comparison and selection.
