摘要
渗流渗压监测是大坝安全监测系统中重要项目之一,而传统的渗流渗压监控模型中存在着变量间相关性不足的问题。借助因子分析法基本原理,以某高拱坝工程为依托,通过对其基础渗流渗压监测资料进行因子分析,得出各影响因子间的关系,分析了渗流量与渗压变化相互关系,揭示出渗流渗压的时空分布规律。实例分析结果表明,该方法对解决大坝渗流渗压监测资料分析中非线性问题可行且有效。
Seepage and seepage pressure monitoring is one of the important projects in dam safety monitoring system.However, there is a problem of insufficient correlation among variables in traditional monitoring model of seepage and seepage pressure. Based on the principles of factor analysis method,a high arch dam project is taken as an example and its seepage and seepage pressure monitoring data is analyzed by factor analysis method to obtain the relationships among each factors.The relationship between seepage flow and seepage pressure change is analyzed and the temporal and spatial distribution of seepage and seepage pressure is also revealed.The results of case study show that this method is feasible to solve the nonlinear problem in the analysis of seepage and seepage pressure monitoring data of dam.
