摘要
本文通过对大量实测数据的因子分析和回归分析，得出了岩体风化定量评价的主要成分，进而讨论了层状火山岩体的定量评价方法，即数据矩阵最大特征值法的应用．
Based on field investigation and the in--situ tests in the south of Zhejian province, this paper discussesthe weathering features and the quantitative assessmant methods of the lay6red volcanic rockmass. Accordingto the factor analysis and the regression analysis, the author points out 3 indexes which are dominated in theweathering assessment of the stratovolcanic rockmass, such as Point Load strength index, P wave velocityand the alteration degree of minerals. The paper also discusses the weathering classification method which iscalled the maximum signature value of data matrix. Using such a method, the zoning standards of weatheringstratovolcanic rockmass can be established.
