摘要
Abstract
Through the field test made on Mayanpo Slope at Xiangjiaba Hydropower Station, the characteristics of the external deformation, deep deformation, groundwater level and stability of the slope with weak interlayers are herein analyzed in detail. The results show that: (1) the slope displacement deformation increases with time and decreases with the increase of depth, while the displacement change rate decreases with time, and basically is consistent with the displacement change stage; (2) based on the consideration of the penalty function contact of the interface between pile soil and the surface of rock mass, a 3-D numerical model of coupling of seepage with strain is established, and then the stability of Mayanpo Slope is analyzed with the strength reduction FEM as well.关键词
