摘要
在施工图阶段,从节约工程投资,加快工程建设的角度,根据大坝建基面(河床段)开挖揭露的实际地质条件,对大坝建基面抬高的优化论证是有必要的。角木塘水电站在建基面的抬高论证的过程中,运用单孔超声波测试、孔壁摄像等勘察手段,进一步对岩体风化线、岩体质量等级、力学参数进行复核,从而论证建基面抬高的地质条件。
In the construction drawing stage,from the perspective of saving project investment and speeding up project construction,the actual geological conditions exposed by excavation of the dam foundation surface(river bed section)are usually considered.It is necessary to optimize the demonstration of the elevation of the dam foundation.Jiaomutang Hydropower Station used survey methods such as single-hole ultrasonic test and hole wall camera to conduct research in the process of raising the foundation surface.The rock mass weathering line,rock mass quality grade,and mechanical parameters were reviewed to demonstrate the geological conditions for the elevation of the foundation surface.
