摘要
在分析宁夏引黄灌区七星渠不同建设年代和运行年限的4座渡槽管理情况的基础上,从施工质量、过流能力进行现场安全检查和质量检测,从结构稳定、结构抗震等方面进行分析核算,基于层次分析的多因素渡槽结构安全评价方法,采用专家打分和赋予权重、一票否决等机制,实现对渡槽的合理评价和有效评估。通过实测和分析核算结果,建立老旧渡槽安全性的等级标准,建立渡槽安全评价的指标体系,形成完整的渡槽安全评价体系。
Based on the analysis of the management of 4 aqueducts with different construction time and service life of Qixing Canal in theirrigation area of Ningxia, it analyzed from the construction quality, the flow ability to conduct site safety inspection and quality inspection;From the aspects of structure stability, structural seismic analysis accounting. Based on hierarchy analysis of aqueduct structure safetyassessment method of the various factors, the weights by using expert scoring and given, one ticket veto, such as mechanism, realized thereasonable evaluation and effective assessment of the aqueduct. Through the analysis of the field and the calculation results, the establishmentof the level of security standards; old aqueduct of safety evaluation index system; form a complete system of aqueduct of safety evaluation.4 flumes of safety appraisal conclusion has been applied to the improvement of irrigation district, for the solid and consolidate the irrigationarea water aqueduct engineering design provides the technical support; using the research results can effectively reveal the cooperatives, theold safety status of water conveyance aqueduct.： Yellow River irrigation area; water conveyance aqueduct; safety appraisal; safety evaluation
