| 摘 要： | 深基坑变形是一个动态的相互依存的过程.在基坑开挖与施工过程中,根据变形观测数据用曲线拟合理论与时序分析方法建立动态预测预报模型,并随着新数据的加入适时修改模型参数.该模型不要求考虑复杂的变形影响因素.工程实例研究表明:该模型预测变形值,其短期误差一般情况下小于5%,较适合于基坑的变形测量与预报.

| Abstract: | Horizontal deformation of the deep pit is a dynamic process.During the excavation and construction,a dynamic combined prediction model,in which curve fitting theory and time-series analysis model is adopted,is established on the basis of measured data.With the addition of new deformation datum,the model parameters are continuously modified.The model is not asked to consider complex factors the deformationof.The practical research has showed that the error between measure and prediction value is mostly below... |
