| 摘 要： | 由于坝区低高程岸坡特殊的地貌和应力环境，其卸荷裂隙的形成机理和地质表现也与高高程岸坡有所不同。采用缓倾角卸荷裂隙的平均倾角、开度和、裂隙密度、平均迹长作为低高程岸坡卸荷带划分的量化指标，结合西南某大型水电工程实际，在现场大量裂隙精细调查的基础上，分析表明4个指标与卸荷强度有较好的响应，继而给出了坝区低高程岸坡卸荷带划分的建议值。

| Abstract: | Low-elevation slope differs from high-elevation slope in genetic mechanism of stress-release crack due to special landform and stress conditions.The stress-release zone of low-elevation slope may be divided on the basis of quantitative indexes such as average dip angle,angle sum,density and average length of stress-release crack which is in response to the actual stress-release intensity.Accordingly,recommendations of division of stress-release zones of low-elevation slope are given. |

| Keywords: | low-elevation stress-release zone dip angle length |
