| 摘 要： | 针对玛尔挡水电站坝址岩体的特性,提出了岩体卸荷分带量化指标,并根据岩体卸荷宏观地质特征、裂隙率、洞壁波速比、透水率等指标,从定性定量角度对坝址岩体进行了卸荷带划分,并系统总结了坝址区岩体卸荷规律,丰富了同类工程岩体卸荷研究的理论与实践。 |
| 关 键 词： | 岩体卸荷 量化指标 卸荷分带 玛尔挡水电站 |

| Abstract: | Based on rock mass characteristics of Maerdang hydropower station,the quantification index of unload zoning was presented and the loosen rock is divided into several different groups according to macro-geology characteristics of loosen rock mass,frequency of joints,the ratio of longitudinal wave velocity of weathered rock mass to that of fresh rock mass and coefficient of permeability,etc,al.In the end,the paper summarized the regular pattern of rock mass unloading systematically and that enriched the theor... |
| Keywords: | Rock mass unloading quantification index unload zoning maerdang hydropower station |
