【摘要】 针对拱坝安全监测中大量的观测数据以及数据之间复杂的相关性,从全坝多测点的测值所形成的相关矩阵中提取整体因素信息,分析各观测变量之间的相互关系,归纳出测量本质相同的变量,使分散复杂的观测数据成果简洁化、整体化,从而为观测资料的整体分析提供一种多元统计分析方法。更多还原

【Abstract】 Aiming at a large quantity of collected data of arch dam safety monitoring and complex pertinence among those data, this paper extracts the integral factors information from corresponding matrix made up of data collected from points of the dam. Through analysis of the interrelation of all kinds of observation variables, the variables of the same survey essence are induced, so those scattered complex observation data are simplified and integrated. On this basis a kind of multiple unit statistic method is provided for integral analysis of arch dam observation information.更多还原
