摘要
介绍了利用Duncan-Chang双曲线E-模型,对尾矿坝初始静力状态进行非线性计算分析的基本原理和计算过程。根据工程地质环境、土体物理力学特性,以主坝中心为剖面建立几何模型。采用GeoStudio软件Duncan-Chang双曲线E-模型,对玲珑金矿尾矿坝进行了非线性静力计算,得到了静力状态下坝内最大主应力、最小主应力、水平和垂直位移、应力水平、最大剪应力和剪应变、最大XY方向剪应力和剪应变,并结合计算结果,对玲珑金矿尾矿坝静力状态稳定性进行了细致分析。
The basic principle and computational process of E-μ hyperbolic model of Duncan-Chang which can be used to do nonlinear calculation for the initial static state of tailing dam is introduced.Based on the geologic condition and physics mechanics parameters of soil layers,the geometric model of the central section of the dam was built.Nonlinear static state of tailing of Linglong gold mine was calculated by Duncan-Chang hyperbolic E-μ model of GeoStudio software.The max main stress,the least main stress,stress level,horizontal and vertical displacement,the max shear stress and strain,and the max shear stress and strain of XY direction in the dam were got.Based on the calculation result,the stability of the tailing dam of Linglong gold mine in static state was analyzed in detail.
