摘要
采用Oden等提出的非局部摩擦模型对压力型锚索锚固段受力状态进行分析,以非局部摩擦模型代替经典的库仑摩擦模型,建立其力的平衡方程,并利用摄动法进行求解。通过对非局部摩擦模型和库仑摩擦模型下剪应力和轴力结果进行比较,并分析了反映非局部效应的相关因素。
Stressing state of anchoring section of pressure anchor cable is analyzed using non-local friction model advanced by Oden instead of the classic Coulomb friction model.Balance equation of the stress is established and its solution is solved using perturbation method.Through comparison between shearing strength and axial force under non-local friction model and Coulomb friction model,correlative factors to non-local effect are analyzed.
