护岸框架减速效果影响因素的定量分析

Factors Affecting the Slowing Effect of Revetment Frameworks Quantitative Analysis

针对护岸框架减速效果影响因素,对相关数据进行处理,使用曲线拟合、相关回归分析、最小二乘估计、F检验、t检验等方法,建立线性相关回归和多元线性分析等模型。运用MATLAB7、EVEIWS6等编程,最终得出长宽比、架空率、框架群长度这3个参数与减速效果之间的经验公式。最后还给出护岸框架群架长率的定义,构造了框架群的架长率、架空率有关减速率的二元线性方程。

Through data processing and methods such as curve fitting,correlation and regression analysis,least squares estimation,F test,t test,linear regression model,multiple linear analysis models are established.With the help of EVEIWS6and MATLAB7,a function of pole's length-width ratio,overhead ratio,length of revetment framework and deceleration rate are established.In addition,a new parameter called frame length rate is defined.Then a function of overhead ratio,frame length rate and deceleration rate are established.
