摘要
本文从四川省雅安市大相岭隧道工程实例出发，以实际工程中最常见的节理倾角为例，用离散元法（UDEC）对不同节理倾角条件下，全断面开挖后（不考虑时间效应）隧道毛洞岩爆发生进行了预测，并加以总结分析。
According to the Daxiangling tunnel engineering in Ya＇an city, Sichuan province, given the most common joint inclination in practical engineering as example, this paper use universal distinct element method to forecast the tunnel rockburst after full - face excavation（ with no - time effection） under different joint inclination circumstance. At last summarize and analyze all of the circumstance.
