摘要
在已有工作的基础上进行组合建模研究,将基于预测有效度的组合预测模型用于建(构)筑物沉降分析.研究显示,组合预测模型的预测精度较单个预测模型的精度高,主要体现在预测误差较小,最大误差<6%.这有助于准确地预测沉降,从而使后期施工组织安排达到最优化,具有一定的经济效益.可以预见,经过模型的不断更新,当实测数据充分可靠时,对其长期趋势的预测可取得可靠的结果.
Based on works of author already finished, this paper do research about combination model, and apply the forecast model to settlement analysis of building. After research, we get some conclusion: accuracy of combination forecasting model is great, forecast error is little, the max error 〈 6%. This study can help to accurately forecast settlement, and even increase economy benefit.
