隧道围岩周边位移的非线性回归分析

The Nonlinear Regression Analysis of Periphery Displacements on Surrounding Rock of Tunnel

实际的工程应用中,由于偶然误差的影响,使得围岩周边位移的量测数据具有离散性,根据实测数据绘制的位移随时间而变化的散点图出现上下波动,很不规则,难以据此进行分析,必须应用数学的方法对量测数据进行回归分析,找出隧道围岩位移随时间变化的规律,为设计和施工提供科学依据。

In the actual project, measured data of periphery displacement is discrete because of accidental error effect and appears varying with time on scattered point diagram that is difficult to carry out regression analysis. It is very important to apply mathematics method to carry out regression analysis on measured data and find out the disciplinarian of the time vs. displacement and provide scientific basis for design and construction.
