深基坑位移变形监测预测模型分析及应用

曲线拟合模型、GM(1,1)模型和BP网络模型是变形监测数据处理分析常用的方法,本文采用3种模型,对深圳市某一深基坑位移变形监测数据进行建模拟合及仿真处理。分析结果表明:BP网络模型的仿真值及精度最高,并采用此模型对该深基坑的位移变形量进行预测。

The Analysis and Application of the Deep Fit Deformation Displacement Monitoring and Forecasting Model

The curve fitting model,GM（1,1） model and the BP network model is the commonly used methods to process and analyze the distortion monitor data;this article uses 3 kinds of models,to carry on the modeling fitting and simulation processing to the deformation displacement monitoring data of a deep fit in Shenzhen.The analysis result indicated that,the BP network model simulation value and the accuracy are highest,and using this model to predict the displacement of the deep fit.deformation.
