高应力比作用下PVA-FRCC抗盐冻寿命预测与分析
Prediction and Analysis for the Life Expectancy of PVA-FRCC on Salt Frost Resistance under High Stress Ratio
摘要
Abstract
Using logarithmic transform GM (1,1) model instead of the original GM (1,1) model, predicting the relative dynamic elastic modulus of PVA -FRCC in salt under the coupled action of frozen -load, and based on the rule of life prediction , forecasting the freeze-thaw cycles.Results show that the established logarithmic transformation of the GM (1,1) model can be used in the medium long term prediction and the accuracy level is one .By adjusting the logarithmic transform model 's parameters c and d to rise the model's fitting and forecasting precision, expanded the scope of the model .The error of the test value and the predicted value of the elastic modulus is less than 5％.Compared with other specimens, the number of freeze-thaw cycles under different stresses is greater than the sample of F 1.5 with 1.5 percent fiber content.关键词
