摘要
文章以改建铁路湘桂线永州至柳州段扩能改造工程七里坪隧道工程实例为依托,考虑了浅埋偏压隧道的地质特性以及围岩受力特征,结合七里坪隧道的支护措施,运用三维离散元软件3DEC对七里坪隧道的锚杆支护方案进行了优化。
Based on the Qiliping Tunnel on the Yongzhou to Liuzhou section of the reconstructed Hunan-Guangxi Railway,the bolt supporting program of the Qiliping Tunnel was optimized using the three-dimensional discrete element software 3DEC,taking into account the geological characteristics and forces of the surrounding rock as well as the support measures of shallow bias tunnels.
