With a water cut-off and slope reinforcement project in Tenglong open-pit mine in Hebei Province as the background, a three-dimensional numerical model was established for finite slope with a retaining wall. Firstly, this numerical model was verified for its validity, and then was adopted in numerical simulation and analysis for the distribution law of earth pressure on the back of wall under translational motion. The results show that as the bench becomes wider, the angle of inclination for sliding surface of finite slope falls down to zero first, and then is gradually increased. When the bench is 9 m wide, the numerical solution of passive earth pressure on the back of wall is almost consistent with the analytical solution in term of its variation rule, which fully verifies the validity of this numerical model. The passive earth pressure presents nonlinear distribution, and the active earth pressure presents convex curve distribution. With both the stability of retaining wall and the construction cost taken into consideration, it is recommended that the slope degree should be set at 30° and the bench should be 9 m wide.

以河北腾龙露天矿止水固坡工程为背景,建立了挡土墙和有限成坡土体的三维数字模型,首先对模型的有效性进行了验证,然后利用该模型对平动条件下墙背上土压力分布规律进行数值模拟分析。结果表明,有限成坡土体滑裂面倾角随平台宽度增大先逐渐减小到零然后逐渐增大;平台宽度9 m时墙背上被动土压力数值解与解析解的变化规律基本一致,充分验证了该模型的有效性;被动土压力呈非线性分布,主动土压力呈凸曲线分布。综合考虑挡土墙稳定性与施工成本,建议将边坡坡角设为30°,平台宽度设为9 m。

以河北腾龙露天矿止水固坡工程为背景,建立了挡土墙和有限成坡土体的三维数字模型,首先对模型的有效性进行了验证,然后利用该模型对平动条件下墙背上土压力分布规律进行数值模拟分析。结果表明,有限成坡土体滑裂面倾角随平台宽度增大先逐渐减小到零然后逐渐增大;平台宽度9 m时墙背上被动土压力数值解与解析解的变化规律基本一致,充分验证了该模型的有效性;被动土压力呈非线性分布,主动土压力呈凸曲线分布。综合考虑挡土墙稳定性与施工成本,建议将边坡坡角设为30°,平台宽度设为9 m。

With a water cut-off and slope reinforcement project in Tenglong open-pit mine in Hebei Province as the background, a three-dimensional numerical model was established for finite slope with a retaining wall. Firstly, this numerical model was verified for its validity, and then was adopted in numerical simulation and analysis for the distribution law of earth pressure on the back of wall under translational motion. The results show that as the bench becomes wider, the angle of inclination for sliding surface of finite slope falls down to zero first, and then is gradually increased. When the bench is 9 m wide, the numerical solution of passive earth pressure on the back of wall is almost consistent with the analytical solution in term of its variation rule, which fully verifies the validity of this numerical model. The passive earth pressure presents nonlinear distribution, and the active earth pressure presents convex curve distribution. With both the stability of retaining wall and the construction cost taken into consideration, it is recommended that the slope degree should be set at 30° and the bench should be 9 m wide.
