摘要
基于有限元强度折减法,以新疆吐鲁番交河故城的典型工程加固剖面为实例,计算分析木质锚杆加固土遗址坡体在静力、地震作用下的安全系数,同时分析木质锚杆长度、锚固角度等因素对其安全系数的影响,评价木质锚杆加固土遗址坡体的可行性,并在此基础上探讨其相关机理及设计中应注意的问题。研究成果可为木质锚杆加固土遗址坡体的相关工程实践提供参考。
The slope stability of a project section of the ancient city of Jiaohe reinforced by wood anchors was investigated using the strength reduction finite element method.The safety factor of stability of the reinforced slope was given under a static load and under earthquake forces.The influences of the wooden bolt length,anchorage angle,and other factors on the safety coefficient were also analyzed.Finally,the wood anchor reinforcement mechanism of the slope was analyzed,which determined the existence of several problems that should be resolved in the future design of reinforced wood anchor slopes.The research results may provide a reference for other soil slope projects reinforced by wood anchors.
