摘要
采用试验和理论方法，建立了裂隙岩体的流变损伤力学模型。利用此模型分析了三峡永久船闸高边坡稳定性，获得了高边坡的长期状态。并与常规弹塑性有限元的计算结果进行了对比分析。
A new model of a rheological damage of jointed rocks is proposed for the slope stability analysis in the paper. An experimental test of granite for some parameters of fracture is conducted on construction site of the Three gorges, A formula used to calculate the rheological cracks is derived under the action of both compression and shear. Then the proposed model is established. The stability of the high slope of the Three gorges shilock is analyzed using the proposed model. We obtain the longtime state of the high slope in the Three gorges The results are compared with that obtained by an elasto-plastic finite element method.
