摘要
通过实地勘测研究,建立了黄河黑山峡大柳树坝址区岩体的滑移—弯曲拉裂松动变形模式.并运用2D—Sig ma有限元程序对其进行分析,充分论证了坝址区岩体的顺层滑移—弯曲拉裂是该处岩体松动的一种重要模式,并给出了若干重要结论.
In this paper, based on the field investigation and analysis of Daliushu Dam located in Heishanxia Gorge, a part of the Yellow River, the sliding and bending deformation model is built up. After AFE (2DSigma) of the Dam, it is testified that sliding and bending deformation is a important model in rock-mass of dams. Some related inclusions are presented in the end.
