从复合材料力学的角度出发,将复合材料剪切滞理论运用于锚杆支护,对锚固体内部应力分布进行了研究,通过剪应力并非线性分布的假设,推导出弹性状态下受到载荷的锚固体轴力分布函数与黏结面剪应力分布函数。通过算例分析锚固体内部交界面的剪应力和锚杆的轴力,绘出轴力和剪力分布图像,并通过数值模拟进一步验证了结果,证明了公式的合理性。
From the perspective of composite mechanics, the shear lag theory of composite materials is applied to the bolt support, the internal stress distribution in the anchorage body is studied. By the assumption that the shear stress is not linearly distributed, the anchored load under elastic condition Body axial force distribution function and bond surface shear stress distribution function. An example is given to analyze the shear stress at the interface of the anchor and the axial force of the anchor rod. The axial force and shear force distribution images are plotted, and the results are further validated by numerical simulation. The rationality of the formula is proved.
