建筑用高分子防水卷材防水可靠性评估方法

Evaluation Method of Waterproof Reliability of Polymer Waterproofing Membrane for Building

通过评估现有防水卷材的防水可靠性,可以为改进防水卷材提供依据。提出建筑用高分子防水卷材防水可靠性评估方法,首先选取耐老化、粘结性能和抗剪性能作为可靠性评估指标;其次,通过S型曲线标准化处理防水可靠性评估指标;最后在专家动态权重法中引入三角模糊数,计算防水可靠性指标的指标值,并利用物元可拓评价方法建立高分子防水卷材防水可靠性评估模型,完成建筑用高分子防水卷材的防水可靠性评估。实验结果表明,所提方法具有较高的评估精度。

By evaluating the waterproof reliability of existing waterproof coiled materials,it can provide a basis for improving waterproof coiled materials.The reliability evaluation method of building polymer waterproofing membrane is proposed.At first,the aging resistance,bonding performance and shear resistance are selected as the reliability evaluation indexes;secondly,the evaluation index of waterproof reliability is standardized by S-shaped curve;finally,the triangular fuzzy number is introduced into the expert dynamic weight method to calculate the index value of the waterproof reliability index,and the matter element extension evaluation method is used to establish the waterproof reliability evaluation model of polymer waterproof coiled materials,so as to complete the waterproof reliability evaluation of polymer waterproof coiled materials for buildings.The experimental results show that the proposed method has high evaluation accuracy.
