工程案例表明，锚索孔道存在一定的弯曲，较多关于锚索的受力分析将锚索简化成是直的，并不能反映实际受力情况。以半平面弹性理论为基础，结合数学计算方法，建立了包含弯曲半径在内的锚固段受力模型，利用弹性理论推导出锚固段在弯曲情况下剪应力关于锚固段长的计算公式，并通过算例给出了锚固段弯曲情况下内、外两侧曲线上的剪应力分布图。与直线情况下剪应力分布图进行比较，分布情况更为合理。

This project actually show that there is certain bent,in the process of making prestressed cable hole,while most analysis on the shear stress around the anchoring segment depicts anchoring segment as straight,and therefore can not reflect the actual situation by force. Based on the half-plane elasticity theory,combining mathematical calculation,anchoring segment contains the bending radius force,inclu-ding the model,was established. Using elastic theory formulas of the lengh of anchoring section at ben-ding shear stress on the anchorage section was deduced and numerical examples were given in the next section of the curved anchoring case and the shear stress distribution on the inner and outer sides of the curve were given. This distribution is more reasonable compared with linear circumstances under shear stress distribution.
