糯扎渡堆石坝施工期心墙沉降统计模型分析

Analysis of Statistical Model of Core-Wall Settlement During Construction for Nuozhadu Rockfill Dam

以糯扎渡施工期心墙沉降为研究对象,阐述了统计回归模型的建立与分析的理论及步骤.借鉴传统统计模型,通过改变模型因子形式建立不同模型,对比分析模型应用结果确定较优且适用的统计模型形式.通过实测资料建立模型并评价模型预测效果,结果表明模型预测精度高,使用较传统模型更为方便,可以作为该工程施工期沉降分析的一个工具,并可为类似工程提供参考.

This paper studies the core-wall settlement of Nuozhadu core-wall rockfill dam in the construction period and describes the establishment and analysis of the theory and procedures for statistical regression model.Based on traditional statistical model,different models are established by changing the forms of model factors;comparative analysis of the results of model application is made so as to determine the appropriate and better statistical model form.Through the measured data to establish the model and evaluate the prediction of different models.The results indicate that the accuracy of model prediction is high and it is more convenient than the traditional model.Therefore,it can be used as a tool for settlement analysis for Nuozhadu project in the construction period and providing a reference for similar projects.
