摘要
采用岩土工程数值模拟软件ZD—σ ,对软岩巷道采用不同支护方案的支护效果进行了数值模拟研究。研究表明 ,锚注支护从加固围岩出发 ,通过内注浆锚杆注浆 ,将巷道围岩胶结成整体 ,大大提高了巷道围岩的强度和承载能力 ,从而保证了巷道的稳定性。
By means of numeric simulation soft ZD-σ for rock and soil engineering.This paper aualyses the support effect for support plans in soft rock roadways.Research results indicate that the strength and bearing capacity of surrounding rock is greatly increased by surrounding rock being glued into a whole with grout injected through grout-injection rockbolts,So that the roadways keep stable state.
