本文提出大坝观测效应定量分析的一种新方法。对混凝土随龄期变化的流变特性的线粘弹性模型进行研究。同时,考虑荷载作用过程的影响。这种方法实际上是确定弹性位移的迭代方法,它引入了一个优于常规定量分析方法的效应分解准则。从实验室和现场试验结果以及混凝土的成份等方面确定混凝土坝的流变特性。最后,附带提出了大坝长期观测位移的分析方法。
This paper presents a new method for quantitative analysis of dam observation effects. The linear viscoelastic model of the rheological behavior of concrete with age is studied. At the same time, consider the influence of the loading process. This method is actually an iterative method for determining the elastic displacement. It introduces an effect decomposition criterion that is superior to the conventional quantitative analysis method. The rheological characteristics of concrete dams were determined from laboratory and field test results and the composition of concrete. Finally, incidental analysis methods for long-term observational displacement of dams are proposed.
