In this paper, two methods of orthogonal numerical simulation test and similar material simulation test are used to study the influence of five factors on the stability of rectangular roadway: roadway width, roadway height, roadway buried depth, lateral pressure coefficient of surrounding rock, and comprehensive strength of surrounding rock. The results show that five factors have influence on the stability of roadway, but the degree of influence is different. The depth of the tunnel and the coefficient of the side pressure of the surrounding rock are positively correlated with the stability of the tunnel; the comprehensive strength of the surrounding rock is negatively correlated with the stability of the tunnel, but the correlation between the width and height of the tunnel and the stability of the tunnel is not obvious. The results of orthogonal numerical simulation test and similar material simulation test verify each other. The results of the field practice of the Fucun coal mine are basically consistent with the results of the two test methods, which shows that the research results have a certain guiding effect on the field roadway support.

矩形巷道稳定性影响因素综合试验研究

本文采用正交数值模拟试验和相似材料模拟试验两种方法研究了矩形巷道稳定性的五个因素：巷道宽度，巷道高度，巷道埋深，围岩侧向压力系数，和围岩的综合实力。结果表明，五个因素对巷道稳定性影响较大，但影响程度不同。隧道的深度和围岩的侧压力系数与隧道的稳定性成正相关。围岩的综合强度与隧道的稳定性呈负相关，但隧道的宽度和高度与隧道的稳定性之间的相关性并不明显。正交数值模拟测试和相似材料模拟测试的结果相互验证。福村煤矿的现场实践结果与两种试验方法的结果基本吻合，表明研究结果对现场巷道支护具有一定的指导作用。
