| 摘 要： | 采用大型计算软件ANSYS，对矩形巷道的围岩松动圈进行数值计算，得出松动圈与其影响因素之间的定性及定量关系，指出应力和围岩强度是松动圈的主要影响因素；虽然巷道跨度对松动圈影响较小，但实际工作 中它的影响仍不能忽略不计。

| Abstract: | A numerical computation is made of broken rock zone around rectangular-shape roadways using ANSYS numerical simulation software, the qualitative and quantitative relation between broken rock zones and the factors affecting them is worked out. It is pointed out that in-situ stress and rock strength are the main factors affecting broken rock zone. Although the span of roadways has a small influence on broken rock zone, it should not be neglected in underground engineering. |

| Keywords: | broken rock zone rock strength in-situ stress ratio of span to height |
