摘　　要：文中针对公路动态变形预计精度低的问题,结合公路下采煤需要进行变形监测这一有利条件,提出了一种不断融入实测数据的高精度开采沉陷动态预计模型,案例分析结果表明,融合实测数据的开采沉陷动态预测模型预计地表最大下沉点的相对误差优于6%。In view of the low prediction accuracy of the dynamic deformation of the highway,combining with the favorable conditions of the deformation monitoring required for the coal mining under the highway,the high-precision dynamic prediction model for mining subsidence that the measured data was incorporated continuously was proposed.Case analysis results showed that the mining subsidence dynamic prediction model fused with the measured data predicted that the relative error of the maximum surface subsidence was better than 6%.
