摘要
层状围岩是经常遇见的一种地质条件,对隧洞爆破施工有很不利的影响。通过对新疆克州布伦口-公格尔水电站引水发电洞进行数值模拟分析,得出层状围岩在爆破开挖时的一些特点,找出容易超欠挖的部位,对超欠挖给出具体建议,为今后设计、施工提供参考和借鉴。
Stratified surrounding rock is one of geological conditions in usual and there are adverse effects on the tunnel Blasting.By using numerical simulation to analysis the stratified surrounding rock of Bulunkou -Konggur hydropower station ,find some features about the stratified surrounding rock when blasting excavation and the easily destroyed location.Give some specific suggestions about over-break and underbreak and provide reference for future design and construction.
