| 摘 要： | 央体强度和变形的各向异性直接影响岩体的稳定。通过对金川二矿区１２１８水平采准巷道围岩岩石及岩体结构面分形、弹性波波速值和巷道围岩位移各向异性特征的具体分析，得出了围岩的各向异性是造成金川镍矿深采准巷道支护变形破坏的主要因素之一，也是巷道围岩变形量大、变形时间长的根本原因的结论。

| Abstract: | The anisotropy of rockmass strength and deformation directly affects itsstability. Through analysis on the anisotropy of rock, constructional surface, elasticwave, displacement of surrounding rock at 1218 heading, the geomechanics model ofsurrounding rock is put forward, and a conclusion is made that the anisotropy is one ofthe factors to induce the deformation and failure of Jingchuan rockmass. |
