摘要
分别建立了不考虑温度因子和考虑温度因子时某混凝土坝坝基扬压力监测统计模型,对比研究了温度对混凝土坝坝基扬压力的影响。研究表明:考虑温度因子建立混凝土坝渗流监测模型,有利于提高建模质量,能更好地描述各环境变量对渗流的实际影响程度,能更准确地对大坝安全作出评价。
The influence of temperature variations on uplift pressure of concrete dam foundation is studied by establishing statistical monitoring models for uplift pressure with or without temperature factors.The research shows that,considering temperature factors,the quality of the model is better,and can describe the influence of environmental variables on seepage more,evaluate the dam safety more accurately.
