建筑物沉降预测模型拟合精度评价

Evaluation on precision of building settlement prediction model

为探讨沉降预测模型拟合精度的评价方法,本文以某大楼实测等时距沉降观测数据为研究对象,利用Logistic和Gompertz曲线对实测沉降数据进行拟合,建立预测模型并进行预测。在此基础上,利用两种评价方法对模型拟合精度进行评价,结果一致,说明两种评价方法均可行,可以用于工程实践。

To explore the method of precision evaluation of the combination settlement model,this paper uses Logistic and Gompertz curve,meanwhile,combining with the measured settlement data of a building,to establish a settlement prediction model. Two methods are used to evaluate the accuracy of the proposed settlement prediction model,and the consistent results show that both methods are feasible and can be applied in engineering practice.
