| 摘 要： | 通过对玄武岩的表观特征、矿物特征、化学特征的研究,发现峨眉山玄武岩的风化作用以物理风化为主,化学风化不明显;运用岩体波速比、岩体的完整性系数、岩石质量指标分别对岩体风化进行了分带;在对岩体分带量化指标研究的基础上,综合确定了峨眉山玄武岩岩体风化分带的量化标准;并以某水电工程边坡为例,运用该标准划分了岩体风化带,总结了斜坡岩体的风化规律.图9,表2,参7.

| Abstract: | Based on the study of the apparent feature,mineral feature and chemical feature of basalts,the result indicates that the physical weathering of Emei mountain basalts is principal and chemical weathering is not obvious. The weathering of rock are zoned in terms of the ratio of wave speed,integrality index of rock mass and rock quality index. Based on quantitative parameters study on the Zoning of rock,the author synthetically determines quantitative standards of belt of weathering. Finally,the slope of a hydropower project as an example,using the standards for dividing the weathered band of rock and summing up the law of weathered rock of slopes. 9figs.,2tabs.,7refs. |
