【摘要】 安全恢复评价曲线(SRAC)是应用主分量分析法降维的思想,根据管网恢复评价指标中存在着一定相关性的特点,用较少的指标来代替原来较多的指标,描点形成安全恢复评价曲线。该曲线很好地解决了管网震后恢复评价过程中,多指标评价带来的选取指标过程中的主观性和由此导致的评价结果的偏差等问题,有效地提高评价的精度和效率。文章阐述了SRAC的原理与构造方法,结合聚类分析,给出了SRAC评价应用算例。更多还原

【Abstract】 With principal component analysis of statistics,this paper constructed a safety restoration appraisement curve (SRAC)which was applied to study safety restoration synthetical appraisement and restoration optimization of urban buried pipe network after seismic disaster. A case was conducted illustrating the way and the processes of safety restoration synthetical appraisement of urban water supply pipe-network after seismic disaster by SRAC,and cluster analysis were illuminated.更多还原
