| 摘 要： | 通过对模型巷道的相似材料模拟试验 ,研究了巷道顶板和两帮的裂隙随载荷变化的分形演化规律 ,得出围岩裂隙的分形维数与载荷比呈线性关系 ,两帮的裂隙分形维数一般大于顶板 ,两帮的裂隙分形演化规律相同。通过测量围岩裂隙的分形维数 ,可定量评价巷道的损伤破坏程度和稳定性。

| Abstract: | Based on the similar roadway model test, we studied the fractal evolution law of the roadway roof and two walls fracture along with the variety of load.The result was obtained that the surrounding rock fracture fractal shows linearity relation with the stress ratio. The two side walls fracture fractal is larger than the roof in general. The fracture fractal evolution pattern of two side walls is similar. Through measure the surrounding rock fracture fractal, the roadway damage degree and its stability can be evaluated. |
