Calculation of stability of anchor support considering prestress

  • 摘要: 对于锚杆支护结构的稳定性计算,在考虑预应力对稳定性的影响时,尚没有有效的方法,尤其是采用圆弧滑移面计算支护结构的稳定性时,都是将锚杆当作土钉,采用规范中计算土钉墙的方法计算安全系数。将预应力作为集中力考虑,给出计算预应力锚杆支护结构安全系数的简化方法,并通过有限元分析软件验证该算法的可行性。
    Abstract: There are no effective ways to calculate the stability of prestressed anchor support considering the effect of prestress. Usually, the anchor is treated as a soil nail, and the safety factor is calculated by the same method of calculating soil nailing provided in standards. A simplified method is provided for calculating the safety factor of prestressed anchor support by treating the prestress as a concentrated force. Its feasibility is verified by finite element software.
