【摘要】 以翔实的现场实测地质资料为基础,对绿片岩的工程地质性质展开了多方面的分析研究;并且运用先进的3D激光扫描工艺,获得了3 500 m2范围内的绿片岩全迹长与单体厚度数据。通过研究得出,绿片岩迹长与厚度均服从对数正态分布,并且二者存在3次多项式关系。最后以研究成果为基础,对绿片岩的处理措施提出了合理建议。更多还原

【Abstract】 A number of green schist rocks develop on the right abutment of Jinping I Hydropower Station,which is one of the most important engineering geology problems.Limited data in previous reseaches resulted in the difficulty in reaching a comprehensive and deep research on green schist rocks.On the basis of the detailed and accurate data measured on site,the engineering geology characteristics of green schist rocks were analyized from multi ple aspects in this paper.Making full use of 3D laser scanning technology,full trace length and individual thickness data of green schist rocks were gotten in the scanned area of 3 500 m2,which made it possible to study their distribution and the relationship between them.It was found that both trace length and thickness of green schist rocks observe logarithmic normal distribution,and show a cubic polynomial relationship between them. At last,based on the results above,treatment measures of different green schist rocks were put forward.更多还原
