应用线性回归分析确定茂名地区土的工程特性

Determination of Engineering Character of Maoming Soil with the Linear Regression Analysis

土层性质参数由于空间特性的变化而具有很大的不确定性,通过理论推导很难获得某些土层性质参数之间的相互关系,但通过应用某些数学方法则可建立土层性质参数之间的经验公式,在经济的前提下获得较可靠的结果,文中在资料积累的基础上,应用线性回归分析建立茂名地区各种土层性质参数间的经验公式,推算未知土参数或检验实测指标的误差大小。

Soil character parameters have large undefinition because of space character.It is very difficult that relations of some soil character parameters are determined passing theory infer.But experience formulas of soil character parameters can be built passing some mathematics methods,using these formulas can get reliable result based on economic premise.The linear regression analysis is a mathematical tool which is used widely,on the basis of material accumulation,it can be used to reach experienced formulas of soil character parameters of maoming region,and using these to calculate the soil engineering parameters or to examine the mearsurd parameters for the error.
