摘要
目的探求桩基基础与灰土地基基础高层建筑物沉降监测数据分析的较优方法。方法应用线性回归模型、时间序列模型、灰色系统模型对桩基基础与灰土地基基础的高层建筑物沉降实测数据进行分析。结果3种方法对桩基基础高层建筑物的数据分析均取得了良好效果,而对灰土地基基础高层建筑物沉降监测数据分析中,时间系列模型要优于线性回归模型、灰色系统模型。结论桩基基础高层建筑物的监测数据分析可以采用线性回归模型、时间序列模型、灰色系统模型,而灰土地基基础高层建筑物监测数据分析更适合选用时间序列模型。
Aim To explore preferable methods on analyzing the settlement data of high-rise building of pole foundation and lime-soil foundation.Methods Applying linear regression model,time series model and grey model to analyzing the settlement data of high-rise building.Results Three methods have obtained the good effect in the high-rise building of pole foundation data analysis.But time series model is better than linear regression model and grey model in the high-rise bulding of lime-soil foundation data analysis.Conclusion Analyzing the settlement data of high-rise building of pole foundation can adopt linear regression model,time series model or grey model;but analyzing the settlement data of high-rise building of lime-soil foundation should adopt time series model.
