摘要:
结合涌水实例用地质法分析了涌水区溶洞暗河形成过程,并成功应用于涌水预报中;对岩溶涌水机理进行了分析,阐述了岩溶发育的条件及施工地质调查的范围与内容;从几方面分析了涌突水的成因及确定施工中安全岩墙厚度应考虑的几个因素,提出了本工程的安全岩墙厚度值及施工策略。
关键词:  , 隧道岩溶涌水机理安全岩墙厚度
Abstract:
Taking the water inflow cases as example, the authors analyze on the forming process of the underground karst rivers in the water inflow zones by means of geology method and applies the analysis results into the water inflow predictions; The authors analyze on the mechanisms of the karst water inflows and expatiate on the karst development conditions and the scope and contents of the construction geological investigations. The authors analyze on the causes for the water inflows/outbursts from several aspects and present the factors that should be considered in the determination of the thickness of the safe rock walls during construction. The authors also provide their recommended thickness of the safe rock walls of the project and recommend some construction countermeasures.
Key words:  , tunnel karst water inflow mechanismssafe rock wall thickness
