摘要
为了解决煤矿围岩非线性大变形问题,进行了恒阻大变形锚杆在静力拉伸下的数值模拟研究。通过室内试验和数值模拟软件Solidworks对恒阻大变形锚杆进行对比分析,结果表明室内试验和数值模拟结果显著一致,恒阻大变形锚杆具有高恒阻值、大变形量的特点,并能在高强度拉力下处于稳定有效的状态,为其在工程中的应用提供了理论和实践依据。
In order to solve the problem of non-linear large deformation of surrounding rock in coal mine, the numerical simulation of large deformation bolt with constant resistance under static tension was carried out.The results of laboratory test and numerical simulation software Solidworks are compared and analyzed. The results show that the laboratory test and numerical simulation are in good agreement. The constant resistance and large deformation anchor has the characteristics of high constant resistance and large deformation, and can be in a stable and effective state under high strength tension,which provides theoretical and practical basis for its application in engineering.
