【摘要】 在对国内外岩体分级方法深入研究的基础上,对岩体分级方法中所考虑的岩体分级因素及对各因素的处理方法进行了系统的归纳和总结。从岩体分级方法的现状来看,虽然目前尚无统一的岩体分级标准,但在岩体分级中应根据岩石的强度、岩体的完整性、地下水条件、地应力状况等多方面因素,进行岩体综合分级上达成了共识,并且国内规范中的岩体分级标准有趋于统一和向国际标准接轨的趋势。更多还原

【Abstract】 All factors considered in the rock mass classification and processing methods are summarized systematically.Although there is no legalized criteria about the rock mass classification right now,people have reached the agreement that the rock mass classification should be based on the strength of rock,the integrity of rock mass,the conditions of groundwater,the conditions of ground stress,etc.Meanwhile,the rock mass classification of the national criteria belongs to the trend of joining the international track.更多还原
