摘要
拉力型锚索、锚杆之锚固段的剪应力是非均布的 ,剪应力分布曲线是以 0为渐进线的单峰曲线。对不同工程类型的锚索、锚杆的实测数据的拟合表明 ,用三参数的高斯曲线来描述锚固段剪应力分布曲线较为贴切 ,并导出了曲线的极值、拐点、积分等特征值 ,讨论了锚固段的有效长度及其安全储备。
Shear stress of anchoring rope(rod)of extensiona l force type is une venly distributed along anchoring section. Distribution curve of the shear stre ss is a unimodal curve with 0 as progressive line. According to fitting measured data in anchoring rope and anchoring rod engineering of different type, it is e xplained that describing distribution curve of shear stress along anchoring sect ion with a Gauss curve (a normal frequency distribution curve) of 3 parameters i s suitable. Characteristic values (maximum value ,inflection point and int egration value)of the curve are studied too. Further, effective length of the s ection and its coefficient of safety are discussed.
