摘要
岩体质量分类是水电工程基础工作中的重要环节。本文用四种不同的岩体质量分类方法 ,选择不同的岩体结构类型对云南某水电工程右岸岩体质量进行了分级。结果表明 ,对于各类岩体结构类型 ,四种岩体质量分类方法所得出的结果非常接近。其对应关系分别为碎裂结构一般为V～IVb 岩体 ,镶嵌结构一般为IVb ～IVa 岩体。次块状结构一般为IVa ～Ⅲb 岩体 ,块状结构一般为Ⅲa ～Ⅱ岩体。并且根据评价结果 ,作出了研究区 6 2 5高程的岩体质量分区图 。
Rockmass quality classification bears great importance in basic work of hydropower engineering project.Four digfferent types of classification methods for rockmass quality are used in this paper to evaluate the rockmass quality of rightbank of a hydropower engineering project.Result shows that the evaluation results to same rockmass structure obtained from four different types of evaluation method are very close.Each rockmass structure has its corresponding rockmass quality grade.Based on the evaluation results zoning map of rockmass quality of right banki 625 elevation is made which will benefit to succeeding work.
