摘要:
为研究锚索预应力损失对二元结构边坡稳定性的影响，构建多因素影响下锚索预应力损失的计算方法，采用有限元软件MidasGTSNX分别建立预应力锚索加固下二元结构边坡在自重及降雨工况下的数值模型，基于有限元极限平衡法分析不同锚索预应力损失率、锚索角度、软化系数及降雨影响层厚度下边坡安全系数的变化规律。研究结果表明：当锚索预应力的损失率在0~80%变化时，二元结构边坡自重工况下的安全系数减小幅度约为12.0%，且锚索倾角越小，安全系数的减小幅度越大；随着锚索预应力损失率的增加，软化系数越小或降雨影响层厚度越大，安全系数的减小幅度越大；降雨入渗和锚索预应力损失的双重影响下，预应力锚索加固下稳定的边坡可能会发生失稳破坏。研究结果可为运营期二元结构边坡的防治提供了理论支撑，具有实际工程意义。
Abstract:
To study the effect of anchor cable prestress loss on the stability of dual structure slopes， the calculation method for anchor cable prestress loss under the influence of multiple factors was constructed. The finite element software Midas GTS NX was used to establish the numerical models of dual structure slope reinforced by prestressed anchor cable under self-weight and rainfall conditions. Based on the finite element limit equilibrium method， the variation laws of slope safety factors under different anchor cable prestress loss rates， anchor cable angles， softening coefficients， and rainfall-affected layer thicknesses were analyzed. The research results show that when the loss rate of anchor cable prestress varies from 0 to 80%， the safety factor of dual structure slope under self weight conditions decreases by about 12.0%， and the smaller the anchor cable inclination angle， the greater the decrease in safety factor. With the increase of the prestress loss rate of the anchor cable，the smaller the softening coefficient or the thicker the rainfall-affected layer， the greater the decrease in the safety factor. Under the dual effects of rainfall infiltration and prestress loss of anchor cable， the stable slopes reinforced with prestressed anchor cables may experience instability and failure. The research results provide theoretical support for the prevention and control of dual structure slopes during operation，and have practical engineering significance.
