摘要:
考虑单支点桩锚支护结构的刚体位移和弯曲变形,建立了锚杆锚固点和支护桩顶的水平位移计算方法.通过分析水平位移的各个影响因素对位移的作用,指出锚杆位置下移会增加锚杆的拉力并进而加大其配筋,但可以减小桩顶在锚杆张拉锚固后的水平位移变形 .以位移控制为目标,通过调整锚杆的位置,对单支点桩锚支护结构的设计进行优化.
Abstract:
Considering the rigid body displacement and bending deformation of the single-fulcrum pile anchor support structure, the horizontal displacement calculation method of the anchor point and the top of the supporting pile is established. By analyzing the effect of various influencing factors of horizontal displacement on displacement, it is pointed out that the downward shift of the bolt position will increase the tensile force of the bolt and increase its reinforcement, but the horizontal displacement deformation of the pile top after the anchor tension and anchoring can be reduced.
