| 摘 要： | 通过对岩体的氡气测试,得到不同高程氡气脉冲值的硐深变化曲线,分析岩体卸荷强度和方式与其氡异常的相关性。岩体卸荷强度愈高,高氡异常值越高,异常深度范围越大,异常特征越明显。边坡集中卸荷拉裂部位、断层及错动带高氡异常,但边坡深部某些顺层断层或错动带异常特征不明显。结果显示卸荷强度和方式与氡气异常特征密切相关。

| Abstract: | Radon gas tests are taken on the rock masses in the right dam-abutment slope at Lianghekou Hydropower Station.Based on these tests,this article draws curves of radon impulse value to depth of each adit at different elevations and analyzes the correlation of unloading strength and unloading way with radon anomaly.The results reveal that,with higher strength,radon becomes more anomalous,and the anomaly extends deeper and wider.Radon is highly anomalous at the tension fractures of concentrated unloading,faults... |
