摘要
地下线路改造施工中道面变形具有不确定性、复杂性等特征。为此,运用灰色理论建立道面变形的预测模型,并结合工程实例验证其有较好精度。鉴于灰色模型在变形预测中仅能预测总体趋势、不能反映预测误差的波动性,通过处理预测误差,定出灰色预测的上、下限值,赋予模型一定的预测区间,改变点预测形式。并依据变形控制线与灰色上、下限曲线的相交位置划分道面变形的安全状态,更为合理地判断施工安全性,为相关工程提供参考借鉴。
In the construction of underground line reconstruction,pavement deformation has characteristics such as uncertainty and complexity.Therefore,the grey model was used to establish a prediction model for pavement deformation,and engineering examples were combined to verify its good accuracy.Given that the grey model can only predict the overall trend in deformation prediction and cannot reflect the volatility of prediction errors,prediction errors were processed to determine the upper and lower limit values of grey prediction,endowing the model with a certain prediction interval and changing the point prediction form.According to the intersection position of the deformation control line and the upper and lower limit curves of grey,the safety state of pavement deformation was divided to more reasonably judge the construction safety and provide reference for related projects.
