    摘要:

    随着长输管道建设迅速发展,其沿线普遍发育的河沟道水毁危险性评价成为研究的热点。依据物元理论和可拓集合理论,构建河沟道水毁危险性评价物元模型。在区域地质环境与河沟道水毁基本特征调查研究的基础上,选取14个具代表性的、可量化的评价指标,引入灰色关联度法求其权系数,采用可拓关联函数确定待评物元与危险性分级之间的关联度和隶属度。通过实际应用和对比分析,证明基于灰色关联度的可拓法用于长输管道河沟道水毁危险性评价具有较高的可信度和良好的实用性。

    Abstract:

    With the rapid development of long-distance pipeline construction, risk assessment of waterlogging is becoming an important research field. On the basis of matter-element theory and extension set theory, risk assessment model of moat waterlogging is established. Based on investigation and studying of the geological environment and the waterlogging basic characteristics, fourteen representative evaluation indexes are selected, and the weights is obtained by the grey relational method. The extension relational function is adopted to define the relational degree and membership between matter-element and risk classification. Through practical application and contrastive Analysis, proving that the extenics mathod is feasible in waterlogging risk assessment of long-distance pipeline.
