摘要
Abstract
Determination of rock mass mechanical parameters constitutes of the core foundation for engineering design and construction.On the basis of field structural plane surveys and indoor mechanical tests,the dominant structural planes of the eastern limestone slope are identified.The rock mass quality is evaluated using RMR,BQ and RQD classification systems.Subsequently,rock mass mechanical parameters are determined via the GSI-based Hoek-Brown strength criterion,and the slope stability is analyzed with the SLIDE software.The results show that 1)The rock mass of the eastern limestone slope is generally characterized by relatively well-developed to well-developed joints and fractures,and the rock mass is moderately broken to broken.2)Combined with three classification methods including RMR,BQ and RQD,the slope rock mass is classified as Grade Ⅳ.3)Numerical analysis by SLIDE software indicates that the eastern slope is currently in a stable state.The research results can provide data support and theoretical basis for subsequent production design and further research of the mine.关键词
