| 摘 要： | 处于不同的地质环境下，玄武岩岩体结构具有不同的状态，在围压原位状态下，岩体结构面镶嵌紧密结合，岩体完整性好，岩体完整性系数与结构面最小间距具有不对应性，应选取完整性系数作为评价指标；而在岩体处于应力松弛状态下岩体完整性差，完整性系数评价指标和结构面间距评价指标具有很好对应性，应选取最小间距作为评价指标。本文通过对西南某水电站坝基岩体在处于不同的地质环境下岩体结构的评价，从而选取岩体完整性系数作为深部岩体结构评价的主要指标。

| Abstract: | Basalt rocks at different geological conditions have a different structures.At first,if the rock is under in-situ confining pressure,the structure of the rock face has close mosaic,the rock has good integrity.The structural integrity of the rock face for rock structure evaluation does not have good correlation with the minimum distance of structural planes.The integrity of the evaluation index should be used.Secondly,if the rock is a state of stress relaxation.The rock integrity is poor.the structural integ... |
