摘要

摘要: 大坝建基面的选择取决于岩体风化程度.玄武岩风化作用受岩体结构控制,岩体的风化首先是沿各类结构面开始,逐渐向岩体内部发展.以西南某水电站为例,通过对某坝址区峨眉山玄武岩风化的表观特征、矿物特征、化学特征进行了研究,结果表明:玄武岩的风化以物理风化作用为主,化学风化作用不明显;断层及层间、层内错动带对玄武岩的化学风化作用无显著影响,现场判定岩体风化界限应重点依据岩体的表观特征,从而为风化界限的现场判定提供了依据.

Abstract: E'mei mountain basalt is one kind of rock mass of hydropower engineering in our country.We determine the surface of dam foundation based on weathering degree of rock mass.Weathering of basalt controlled by rock mass structure,start on surface of various rock mass structures,and developed into interior gradually.Taking one hydropower station of the southwest China an example in this paper,the authors study on the weathering of apparent characteristics,mineral characteristics and chemical characteristics of E'mei mountain basalt on dam-site.It suggested that weathering of basalt mainly is physical weathering,and chemical weathering is not obvious,and fault,interlaminar and intrastratal disturbed belt are not obvious effect in chemical weathering on the basalt.Judging from the boundary of rock mass,weathering on the site is mainly depend on apparent characteristics of rock mass,finally the paper provide reference for judging weathering boundary on the site.
