深厚表土层地区混凝土井壁变形监测及灰色模型预测

基于深厚表土层地区混凝土井壁破裂变形预测及井壁破裂预防性信息化施工的需要,介绍混凝土井壁变形自动监测的原理、方法及监测特点,基于实测监测信息,建立某井壁混凝土变形预测非等间隔灰色预测模型,实测与预测结果表明该模型可用于混凝土井壁变形超前预测.

Concrete shaft lining deformation monitoring in thick alluvium region and grey model forecast

Based on the demand of concrete shaft lining deformation forecasting in thick alluvium region and shaft lining crack preventive information construction,the paper focuses on the principle,methods and monitoring features of concrete shaft lining deformation auto-monitoring.Concrete shaft lining deformation forecast non-equidistant sequence grey model is built according to the in-situ monitoring information.The in-situ measured and forecast results show that the model can be used for advanced forecast of concrete shaft lining deformation.
