摘要
结合具体工程实例,阐述了在隧道的灌浆工程作业下,在断层带相对较宽、断层处塌方严重情况下,通过合理确定注浆参数,改变注浆顺序,调整注浆浓度和控制注浆压力等方法进行隧道预注浆加固的过程,并得出了注浆加固成功的结论。
Combined with specific engineering example,the tunnel slurry injection process under fault relate wide and serve collapse in fault position and tunnel slurry injection working by proper determining grouting parameters,improving grouting procedure,regulating grouting concentration and controlling grouting pressure was illustrated,it concluded that grouting reinforcement was successful.
