西南某水电站岩体质量分级研究

介绍了水利水电工程地质分类、RM R分类和Q系统分类等3种分级法的具体使用和评价标准,并以西南某水电站为例,将这3种分类方法对其坝区围岩分类的结果进行了对比和相关性分析,得出了该水电站围岩合理、科学的评价分类结果。依据此评价结果,绘出了坝区岩体质量分级图,准确显示了坝区的岩体质量特征,证实了3种分级法在该类岩体分级的适用性和统一性。在充分调查和资料掌握的基础上,对岩体工程地质分类在实际工程中的应用提出了具体的指标和实际的操作法。

The Rock Quality Classification Study of Certain Hydroelectric Station Foundation in the Southwest

The paper introduces evaluation standard and the operation method of surrounding rock classification in Hydroelectrics, RMR and Q system, using the three classification method to get the classifiction result of the surrouding rock in a southwest hydroelectric powerstation and the correlation analysis among the three results,then draw the scientific and reasionable conclusion in classification of the hydroelectric power stration. According to the appraisal results ,zoning maps of rock qualify at different levels and different areas of appraisal survey are made, which explicitly indicates the character of the rock mass in the areas and confirms the fitness and oneness . Based on the of files ,the actual indications and using methods are accessed in geolo plenty surveys and the acquaintance gic rock classification in engineering.
