摘要
在地面地质调查和勘探的基础上,对河南天池抽水蓄能电站岩石风化和蚀变特征进行分析,得到岩石风化的主要部位和风化带下限深度以及蚀变的主要部位和蚀变带深度;通过室内岩石物理力学性质试验得到中等风化、微风化—新鲜的岩样的物理力学性质参数;对下库坝址平洞和露头剖面的蚀变岩开展了薄片鉴定、扫描电镜及其能谱分析、电子探针测试、X射线衍射等试验,证明了蚀变矿物的存在.
On the basis of ground geological survey and exploration,rock weathering and alteration features of Tianchi Pumped Storage Power Station of Henan Province were analyzed,then the main part and depth of weathering and alteration of rock were given.The physical and mechanical properties parameters of moderately weathered,slightly weathered to fresh rock samples were obtained through the test of indoor rock physical and mechanical properties.Thin section analysis,scanning electron microscopy and spectroscopy,electron probe tests,and X-ray diffraction experiments were carried out on the altered rock of lower reservoir dam site adit and outcrops.The results proved the existence of alteration minerals.
