基于双参数线性化回归的基坑变形分析与预报

摘要

通过变量代换,给出了基于非线性函数空间的双参数线性化回归模型库,并提出了不同样本数据子集回归效果评价的综合指标.借助工程实测数据与Matlab程序,对深基坑施工各阶段的累计变形量与时间因子的关系作了综合分析,验证了线性化回归在监测数据整体分析与实时预报中的可行性.%Through the variable substitution, linear regression models with two parameters are given in space of nonlinear functions. Based on the model establishment and significance test for simple linear regression, the comprehensive evaluation index is put forward for regression effect with different sample data. With measured data and Matlab program, the relation between cumulative deformation and monitoring date at each stage is analyzed. Then, the linear regression method is verified feasible for monitoring data analysis and real-time prediction.
