摘要
笔者以某抽水蓄能电站蚀变花岗岩为例,研究不同蚀变程度对花岗岩物理力学性质的影响.通过统计分析蚀变花岗岩物理力学性质试验结果,参考岩石坚硬程度分级,并结合工程需要,提出蚀变花岗岩的分级标准,并建立蚀变等级与蚀变花岗岩物理力学性质之间的联系.结果表明:蚀变越严重,物理力学性质越劣化;轻微蚀变花岗岩可以有条件地使用,中等蚀变花岗岩可以限制使用,而强蚀变花岗岩使用则需要专门研究.研究结果为其他类似工程蚀变花岗岩分级和应用提供参考.
Abstract
Taking the altered granite of a pumped storage power station as an example,the influence of different alteration degrees on the physical and mechanical properties of granite was studied.Based on the statistical analysis of the test results of the physical and mechanical properties of altered granite,the classification standard of altered granite is put forward by referring to the classification of rock hardness and combining with the engineering needs,and the relationship between the alteration grade and the physical and mechanical properties of altered granite is established.The results show that the more serious the alteration is,the worse the physical and mechanical properties are;Mild altered granite can be used conditionally,medium altered granite can be restricted,and the use of strong altered granite needs special study.The research results provide reference for the classification and application of altered granite in other similar projects.
