物元可拓模型在渠首冲砂闸安全评价中的应用

Application of matter-element extension model in safety evaluation of sand-flushing sluice of canal headwork

本文概述了物元可拓理论,并建立了物元可拓模型。通过确定铁力市王杨渠首冲砂闸的经典域物元矩阵、各指标权重和综合关联度,建立了水闸安全评价指标体系和安全评价标准,利用物元可拓模型对铁力市王杨渠首冲砂闸进行了安全综合评价,并依据水闸安全鉴定标准将铁力市王杨渠首冲砂闸判定为三类闸。

This paper summarized the theory of matter-element extension, and established the matterelement extension model. The safety evaluation determining the classical domain matter element index system and standard for sluice were built by fist matrix, the weight of each index and the comprehensive dependent degree. The matter-element extension model was used to assess the comprehensive safety status of the sand-flushing sluice of Wangyang canal headwork in Tieli City. Based on the safety appraisal standard for sluice, the sand-flushing sluice of Wangyang canal headwork was classified as a third kind dangerous sluice.
