【摘要】 在水电工程建设中,往往会对边坡进行开挖形成缓坡平台,进而形成新的临空面,可能对边坡稳定性产生不利影响。该文通过野外地质调查,对某抽水蓄能电站料场边坡变形体边界进行划分,并导入三维离散元建模,对变形体位移值进行计算分析。结果表明,该边坡变形位移较大,可能沿1200m平台产生滑动,处于欠稳定状态。更多还原

【Abstract】 In the construction of hydropower projects,the gentle slope platforms are often formed by excavation of slopes,and then a new free surface is formed,which may have adverse effects on slope stability. In this paper,based on the field geological survey,the boundary of deformation body of a pumped storage power station material field slope is divided,and the three-dimensional discrete element modeling is introduced to calculate and analyze the deformation value of the slope. The results show that the deformation displacement of the slope is large,and the slope may slide along the 1200 m platform,which is in an unstable state.更多还原
