| 摘 要： | 青云山特长隧道采用以综合地质编录、素描为基础、并结合多种钻探的预报方法,形成了"长短结合、点面结合、定性分析与定量实测相结合"的施工地质超前预报技术,提高了隧道穿越复杂地段的断层带、挤压破碎带、涌水带等不良地质体的超前预报效果,较好地修正了勘察设计阶段的地质资料,有效地控制了施工安全风险,优化了相应的工程措施,为同类工程施工积累了经验。

| Abstract: | The geological forecast method-which integrates geological recording,mapping and various explorations,and combines long and short measuring,qualitative analysis and quantitative data collection-was applied to the Qinyunshang Tunnel.The forecast accuracy was improved regarding tunnel crossing of a complex fault,squeeze fractures and the unfavorable geological condition of water inflow.This method allows for corrections of the geological documents from the survey and design phases,effectively controls constru... |
