针对接触带巷道监测试验采集到的变形数据序列的非等时距问题,分别运用分段三次Hermite插值和嵌入时间影响因子Δt并重构模型背景值两方面分析了接触带巷道非等时距变形量的建模方式,建立了非等时距预测模型,通过同一组非等时距监测值的计算验证表明,含Δt的非等时距Verhulst模型更适用于接触带巷道围岩变形量预测,预测精度由勉强合格提高到好。 Aiming at the problem of non-isochronous time series of deformation data series collected in the roadway monitoring test of contact zone, the three-time Hermite interpolation and the embedding time influence factor Δt are respectively used to reconstruct the background value of the model. Equal time-lag prediction model is established. The same group of non-isochronous monitoring values ​​show that the non-equidistant Verhulst model with Δt is more suitable for the prediction of surrounding rock deformation in the contact zone, Predictive accuracy is improved by barely qualified.
