摘要
梁式渡槽作为大型输水工程中重要的交叉建筑物,其安全与稳定性直接决定了输水干渠的正常运行,一旦失事将会造成严重的灾害和社会经济损失。选取影响槽墩冲刷破坏、裹头边坡失稳、槽身挡水3大类12个风险指标,利用层次分析法确定主观权重、熵权法确定客观权重、博弈论赋权法确定组合权重,建立云模型风险评估模型。选取某大型输水工程6座典型梁式渡槽为研究对象,开展实例研究,结果证明本研究为大型输水工程交叉建筑物的风险评估研究提供了新思路。
As an important cross structure in large-scale water transportation project,the safety and stability of the beam-type aqueduct directly determine the normal operation of the main water transportation channel.Once it fails,it will cause serious disasters and socio-economic losses.In view of this problem,12 risk indicators of three major categories affecting the scouring failure of aqueduct piers,the instability of wrapped head slope,and the water retaining of aqueduct body were selected in this paper to establish a cloud model risk assessment model,using the analytic hierarchy processto determine the subjective weight,the entropy weight method to determine the objective weight,and the game theory weight method to determine the combination weight.Six typical beam aqueducts of a large water conveyance project were selected as the research objects for case studies.The results showed that this study provided a new approach for risk assessment of cross structure in large water conveyance project.
