摘要
为了揭示西部干寒地区引水明渠在全寿命周期内存在的不安全因素,避免明渠病害频发给社会经济带来的巨大损失,针对西部独特的气候地质条件,依据《灌溉与排水渠系建筑物设计规范》,结合专家咨询和前期笔者对该地区明渠病害特点的研究,构建了引水明渠安全评价指标体系,利用灰色Euclid理论模型对其进行全寿命周期安全评价。采用IAHP求解各指标权重,利用灰色Euclid理论确定各指标间的关联度,最后综合得到相对灰色Euclid加权关联度并对引水明渠安全程度进行评价。以西部干寒地区4段明渠为例,应用灰色Euclid理论模型进行安全性评价,结果与实际情况一致,表明该模型对西部地区引水明渠安全评价的有效性和实用性,可为明渠的安全管理提供重要依据。
In order to reveal the unsafe factors in the whole life cycle of the water diversion open channel in the dry and cold areas in western China,it is necessary to avoid frequent diseases of open channel in this area,which brings great losses to society and economy. In this paper,for the western dry and cold regions unique climatic and geological conditions,according to the Code for Design of Irrigation and Drainage Canal System Structures and combined with the expert consultation and the previous team＇s study on characteristics of open channel diseases in this area,this paper established the safety index system of diversion channel and used the gray Euclid theoretical model to evaluate the safety of the whole life cycle. This paper used IAHP to solve the weight of each index,used gray Euclid association theory to determine the correlation between the indicators and finally got the relative gray Euclid weighted correlation degree of diversion channel safety sort. Taking four open channel sections in the dry and cold areas of western China for an example,the paper applied the gray Euclid model to evaluate the safety. The conclusion was in agreement with the actual situation. The research result shows that the model is effective and practical for the safety evaluation of the open channel in western China and it can provide an important basis for the safety management of open channel.
