摘　　要：为揭示岩体劣化作用下锚索预应力补偿机制,本文基于Abaqus数值模拟,开展了锚索预应力在岩体劣化作用下损失及补偿数值模拟实验,并在验证模型可靠的基础上,分析了不同劣化率下锚索预应力损失和预应力补偿机制,研究结果可为预应力锚索锚固的边坡灾害防治提供相关依据。In order to reveal the compensation mechanism of anchor cable prestress under the action of rock mass deterioration,based on Abaqus numerical simulation,this paper carried out numerical simulation experiments on the loss and compensation of anchor cable prestress under the action of rock mass deterioration,and analyzed the prestress loss and compensation mechanism of anchor cable under different deterioration rates on the basis of verifying the reliability of the model.The research results can provide relevant basis for slope disaster prevention in prestressed cable anchorage.
