摘要
应用基于Mindlin问题位移解的模型、双曲函数模型、基于抗拔作用的力学模型等3种理论模型分析了锚杆荷载传递机理和锚杆表面剪切力和轴力沿锚固长度的分布规律及其影响因素.就锚杆荷载传递机理问题,对这3种模型作了比较,并对它们作了评价,指出各自的适用性,进一步为岩土工程中锚杆的力学分析和设计提供理论依据.
The model based Mindlin＇s solution of displacement, hyperbolic function model and the model based uplift effect are applied to analyze load transfer mechanism on bolts. The distribution of frictional resistance and axial force along the anchoring length and influence factors are obtained. Three models are compared in the view of load transfer mechanism on bolts. The difference and sameness of three models are analyzed and valued. They are suggested to apply in geotechnical engineering. A theoretical principle of design of bolts is provided for anchor projects.
