摘要
在边坡的变形监测数据分析中,可以依据任意抽取的某一时段的监测样本数据做出变量间关系的散点图和变量之间关系的回归线,它能够最理想地反映监测数据变量间的关系。以抽取的2个变量的一批测量数据作为样本数据,建立变量之间回归方程,并对这一回归方程进行检验,以确定其能否比较可靠地反映2个变量之间的关系,如果回归方程可靠,就可通过回归计算的结果,对边坡位移量趋势进行分析,从而掌握变形体变形的动态和特征,对被预测变量进行有效的预测。
In analysis on the deformation monitoring data of the slope, scatter diagram and regression line of relationship between varia-bles can be drawn respectively in accordance with the data of the monitoring samples taken randomly at one period.They can ideally re-flect the relationship between the monitoring data variables .Based on one batch of the monitoring data of two variables as the sample da-ta, the regression equation between the variables is established.Meanwhile, this regression equation is verified to secure it can reliably reflect the relationship between the two variables.Provided that the regression equation is reliable, tendency of the slope displacement can be analyzed by application of the results of the regression calculation.Accordingly, development and characteristics of the deformation of the deformation mass can be learnt and the effective prediction can be performed to the variable to be predicated.
