摘要
通过对非等时距原始数据等时距处理和累减构建基于灰色理论的微分模型的方法,成功建立了高速公路高填方路堤沉降的非等时距灰色预测模型。并在此基础上,引入加权因子,优化重构了背景值函数。优化的非等时距灰色模型在沉降监测的实践应用中,预测结果经检验显示,优化的模型效果更佳。
Unequal Time-Interval Gray model for embanment settlement of expressway is established successfully,through the quantitative treatment of original Unequal Time-Interval data and building the differential equation based on gray theory by IAGO.And based on this,a weighted factor is introduced,the background value function is Optimized and reconstructed.The Optimized Unequal Time-Interval grey model is applied in the settlement monitoring and the Predicted results by the test is much better.
