一、缝管式锚杆力学模型的建立为了便于计算和分析,在尽量不影响计算结果的前提下,对缝管式锚杆的受力做如下简化:1.假设锚杆受力对称;2.视径向垂直分布力P(θ)为垂直的均匀分布,且沿整个横截面表面分布;3.将切向分布力τ(θ)假设为C_θ+C_1θ+C_2θ~3的形式;4.不考虑锚杆在缝端所受集中力的大小。
First, the establishment of mechanical model of seam anchor In order to facilitate the calculation and analysis, as far as possible without affecting the calculation results under the premise of the force of the seam tube anchor to do the following simplification: 1. Assuming anchor force symmetry; 2 The vertical distribution of radial force P (θ) is perpendicular and uniform distribution, and distribution along the entire cross-sectional surface; 3 tangential distribution of force τ (θ) is assumed to be C_θ + C_1θ + C_2θ ~ 3 form; Does not consider the bolt in the seam end by the concentration of the size of the force.
