| 摘 要： | 在充分研究隧道施工常见不良地质类型和超前地质预报技术的基础上,将隧道施工常见的不良地质分类与不同阶段超前地质预报技术的精度结合提出隧道施工不良地质预警分级及预案。隧道施工超前地质预报因方法不同其预报精度不等,且各种不良地质与隧道的空间关系不同而对隧道施工的危害也不同。考虑到预报精度和不良地质类型,作者将隧道施工不良地质进行了预警分级。针对某级某类不良地质体建立了相应的防控预案,以防为主,紧急情况有相应的处治措施。并以绿、蓝、黄、红四种颜色代表不同的危险等级在洞口标示起到警示作用,加强施工人员的安全意识,从而保证隧道施工过程的安全。

| Abstract: | Based on researching different bad geological body types and geological forecasting technology in tunnel,this thesis combines the different types of bad geological body and the precision of geological forecasting technology to put forward bad geological body emergency plan.Because of different geological forecasting methods,it has different forecasting precision,and different types of bad geological body at different situation have different influence on tunnel excavation.Considering geological forecasting precision and bad geological body type,author have established an alarm and emergency plan for bad geological body to prevent from accident happening at the certain grade and type of bad geological body.The plan makes use of four colors of green,blue,yellow and red at tunnel port to show different danger grade,warning builder to defend bad geological body,and improving caution awareness,SO as to ensure tunnel excavation safety and reduce work risk. |
