【摘要】 从变位——剪应力理论入手,分析了拉力型土锚的受力机理。以分散压力型土锚为例,确定了单孔复合型土锚的最优分段长度。并从理论上对其极限承载力与拉力型土锚极限承载力进行了比较,得出了一些比较切合实际的结论。更多还原

【Abstract】 the shear stress distribution of the tension soil anchor is analysed with the theory of displacement-shear stress in this paper,then the proper unit anchor length of the SBMA (the single bore multiple anchor) is determined by analysing the multiple compression soil anchor. The ultimate bearing capacity of the SBMA is compared with that of the tension soil anchor,and some advisable conclusions are got.更多还原
