摘　　要：为保障三峡升船机塔柱结构安全和升船机的运行维护,需要对塔柱外观变形进行检测。塔柱外观检测受通航、天气和作业条件等诸多因素影响,检测质量和工期难以保障,对检测方案进行科学高效评价和比选非常必要。针对塔柱主要区段结构特点,提出了多种外观检测方案,并采用现场调查和专家投票相结合的方式对每种方案优劣进行综合评价。通过专家打分和现场计算为各指标赋值,运用熵值法对指标进行赋权,形成了主客观结合的综合评价体系。实践表明:通过该综合评价方法优选的方案检测工期比预算缩短18.5%,采集画面总合格率在99.6%以上,可为类似高耸建筑外观检测方案决策提供参考和借鉴。To ensure safety of the tower structure and the operation-maintenance of the Three Gorges ship lift,it is necessary to detect the deformation of the tower appearance.Because of the tower appearance inspection is easily affected by many factors such as navigation,weather and working conditions,the inspection quality and construction period are difficult to guarantee.Therefore,it is necessary to carry out scientific and efficient assessment and comparison of the tower appearance inspection scheme.In this paper,according to the structural characteristics of the main sections of the tower,several appearance inspection schemes were proposed,the advantages and disadvantages of various inspection schemes were comprehensively assessed by field investigation and expert voting.Through expert scoring and field experiment calculation,each index was assigned,and the entropy method was used to weight the index,forming a comprehensive assessment system with subjective and objective combination.Practice showed that the scheme optimized by the comprehensive assessment method had high detection quality and short construction period,which can provide reference for the decision-making of the appearance inspection scheme of similar high-rise buildings.
