摘要
在本文中，作者应用所编的ＦＶＰ程序，对金川镍矿１２００中段试验巷道进行了粘弹─粘塑有限元计算，其中将锚杆的作用分别处理成锚固体单元和杆单元。所得洞周位移计算值与实测值吻合较好，并对比了使用锚固体单元和杆单元的计算差异。
In this paper the Viscoelastic - Viscoplastic FEM for a test gallery ofJinchuan Nickel Mine With FVP program developed by the authors is given, in whichthe actions of rock bolts are simulated with bolted body elements and bar elements respec-tively. The calculated side wall displacements coincide well with the values measured.The results of calculation using bolted body elements to that with bar elements are com-pared .[
