边坡滚石水平抛掷距离的多元分析

The Multifactor Analysis on the Horizontal Throw Distance of Slope Wall Fallen Stone

边坡滚石水平抛掷距离是研究露天边坡组成的重要依据之一，它关系到边坡安全和生产作业安全。本文在多因素多水平试验数据基础上，通过变量的相关性分析，找出影响滚石水平抛掷距离的显著性因素，为垂直下落高度ｘ和边坡坡面角ｙ，并通过多元正交多项式回归，在考虑ｘ与ｙ的交互作用下得出了函数关系式Ｌ（ｘ，ｙ），并对其应用问题进行了讨论。

The horizontal throw-distance of slope wall fallen stone is one of important basis of slope design and it have relation to slope safety and word safety.First,this paper on the basis of the experimental data in multifactor and multilevel using interrelation analysis of factor to find out notability factor in fall altitude (x) and slope angle(y).Second,with mutual effect of x to y using perpendicular polynomical regression to get regression function of L(x,y).Lastly,the application of L(x,y) is discussed.
