摘要
介绍了华莹山公路隧道围岩应力测试所采用的水力劈裂技术的测试方法和成果,分折了地下洞室围岩应力的分布状态及影响围岩应力的主要因素,以及岩体应力值与岩爆的关系。
The measurement method and results of in-situ stresses and rock burst for surrounding rockmass of Huayingshan tunnel of Guang-Yu expressway are presented. The relationship between stress state and rock burst is discussed,and the stability of surrounding rockmass of the tunnel analysed.
