【摘要】 仙蠡桥水利枢纽工程是无锡城市防洪工程中单项规模最大的工程，总投资达到2.98亿元；是无锡城市防洪工程第一个开工建设的枢纽工程，它的建设为水利工程尤其是无锡城市防洪其它枢纽工程的建设提供了有益借鉴。 针对仙蠡桥水利枢纽工程建设过程中设计与施工阶段存在的难点，在以下几个方面进行科学分析，提出相应的解决办法。主要包括：水泵、进出水流道模型装置试验研究，验证模型的装置效率，确定进出水流道形式；通过北枢纽整体水工模型试验研究，提供对外河防冲槽末端及梁溪河与京杭运河交汇处的最大垂线平均流速等。提出间隔流墩布置及合理长度；针对南枢纽施工期间必须不断通航施工的特点，提出施工导流措施；为保证调水改善水环境，实现梁溪河水与京杭大运河水分流，修建“水下立交”而进行方案比较、分析；为尽量满足景观要求，降低节制闸建筑物的高度，通过闸门设计方案比较，采用卧倒式闸门。在工程施工中，针对顶管工程的施工特点及所遇到设备、工期、施工工艺等问题，提出切实可行的技术方案，解决因地质原因、设备选型所造成的施工难题；针对工程的工期矛盾，通过工期优化，保证工程顺利实施。更多还原

【Abstract】 Water complex project of Xianli bridge is the maximal and earliest Single project of Wuxi city flood-prevention project, with investment reaches RMB298 million; It has provided the c experiments for Hydrolic Engineering especially for other projects of the Wuxi city flood-prevention project.For the difficulties of this project’s construction and designing, we carried out scientific analysis , suggested corresponding solutions in the following aspects. Including: The water pump, streams getting in and out model device experiment studying, verify the model device efficiency, ascertain the form of passing in and out of streams; Studying north key position overall hydraulic model to provid the average maximal vertical line flow rate on the external flood-prevention slot converge with Jing Hang Canal ,Liangxi river .Suggest the arrangement and the rational length of gap stream block; As it had to be on service unceasingly during that period when south key position is under construction, we adviced the proper flow-guiding measure ; To ensure that transfer water improves water environment and to realize division of Liangxi river water and Jing Hang Canal , compared schemes to build "underwater-crossing"; reduced height of the check gate building to suit the demand of landscape, adopted to ground dyadic sluice gate by comparing gate design plans.In construction , proposed the practical feasible technology scheme, considering the characters of construction and equipments, time limit, technical and ect, soluted problem cause of geology and equipment choices cause , equipment; Specifically for contradiction of the project time limit, optimizing time for a project to ensure that the project is put into effect smoothly.更多还原
