| 摘 要： | 本文根据应用较广的胶结锚杆的变形特性和荷载形式,考虑到胶结锚杆杆体、胶结层和岩体的不同物理力学性质,建立了一种新的模拟单元,它包括模拟胶结锚杆的胶结层、锚头部位的胶结层、杆体以及对岩体不连续面的锚钉效应的六节点等参数胶结单元、五节点等参数胶结单元、三节点等参数的杆体单元和二节点锚钉单元。

| Abstract: | On basis of the deformation behaviour and load form of grouted bolts widely used at present, and considering the difference in mechano-physical characteristics between the bolt and grout,we have developed new element models to model the grout, head grout, bolt, and the bolt inserted across the discontinuities, respectively. They include 6-node isoparametric grout element (atso used for modelling the discontinuities of rock masses) , 5-node isoparametric grout element, 3-node isoparametric bolt element, and 2-node bolt'element. |
