压力型锚杆作为新型锚杆型式,克服了拉力型锚杆黏结应力峰值突出、防腐性能较差、杆体无法拆除等性能缺陷,具有独特传力机制和良好工作性能。利用无限体内一点受集中力作用的Love位移与应力函数解,推导出浆体与岩土体界面间的位移及剪应力分布曲线,以及通过使用Mathmatica及Matlab等数学工具求出锚固体周边岩土体内各点的位移等值线,并采用Ansys数值模拟方法进行验证,得出压力型锚杆锚固段的锚固效应特性。
As a new type of anchor, the pressure-type anchor overcomes the outstanding stress sticking stress of the tensile anchor, poor corrosion resistance and unworkability of the rod, and has a unique force transmission mechanism and good working performance. By using the Love displacement and stress function solution with infinite concentrated force in the body, the displacement and shear stress distribution curves of the interface between slurry and rock and soil are deduced, and the mathematical model of the surrounding rock mass The displacement isoline of each point in the body is verified by Ansys numerical simulation method, and the anchoring effect characteristics of the anchorage section of pressure anchor are obtained.
