    THE DAM ROCK-MASS QUALITY EVALUATION AND TREATMENT OF DEFECTS OF THE CROWING GRAVITY DAM OF GUANDI HYDROPOWER STATION

    • 摘要: 官地水电站大坝属高重力碾压混凝土坝,地质条件复杂,建坝岩体质量合理准确的评价以及缺陷的有效处理对大坝的稳定安全至关重要。本文根据素描及实际开挖揭露地质情况,通过地质定性评价与物探定量评价对重力坝坝基开挖岩体进行综合评价,结果显示开挖岩体揭露地质与前期勘察基本一致,岩体质量总体满足建坝要求,对今后重力坝坝基岩体评价有一定的指导意义。

       

      Abstract: Crown land is a high gravity dam hydroelectric complex geological conditions, rock dam reasonably accurate evaluation of the quality and effective treatment of defects in the dam's safety is essential. Based on the sketch and the actual excavation of exposed geological conditions, through the geological documentation of qualitative evaluation and quantitative assessment of the gravity geophysical detection of rock foundation excavation comprehensive evaluation results show that rock excavation to expose essentially the same geology and previous surveys, the overall rock mass dam to meet the requirements. It has certain guiding significance for the rock mass evaluation of gravity dam foundation in the future.
