摘要
以伊利石软岩巷道作为研究对象,采用数值模拟方法对其开挖后的伊利石围岩应变场和塑性场的分布情况进行了ANSYS数值模拟及计算结果分析。结果表明：开挖后巷道围岩在X、Y方向的应变分布处于左右对称状态;围岩应变和塑性区域为1倍～2倍巷道直径,巷道顶板和边墙连接处、边墙和底板连接处的应变最大。
The illite soft rock tunnel was taken as the studied object. The strain field and plastic field of the illite soft tunnel excavated were studied by used of the ANSYS numerical simulation. The result is that： the strain of the tunnel surrounding rock after excavation is in the symmetric state on X and Y. The strain and the plastic zone of the surrounding rock is 1 time-2 times the diameter of the tunnel. The largest strain is located on the two junctions, which one is the roof and side wall junction, other is the side wall and bottom plate Junction.
