摘要
为判断黑河金盆水库工程大坝右岸斜坡的性质(是变形体或滑坡),并有利于指导工程施工,在进行了详实的野外地质调查之后,作者分析认为该斜坡实际上为一古滑坡。在地表及平硐调查中所见滑坡周界清晰,变形破坏现象明显,为查明滑坡性质提供了客观证据。近两个月的位移监测资料亦进一步证实了上述结论的正确性。在此基础上,考虑到工程的重要性及施工时间的紧迫性,作者建议对底滑面以上的滑坡堆积体予以全部开挖清除。
In order to ascertain the property of sloper of the engineering construction,a lot of work have been done,especially including the field investigation in detail.The author discovered that the slope is an ancient rock slide.The line of landslide limitation and deformation-failure features are rather certain in the surface,and so are in the drift.All of these features can confirm the above conclusion.Also,the result of displacement measurement in the slope area proved that the slope is a landslide.On considering the importance of engineering construction and the time,the author suggest that the sliding mass should be excavated.
