摘要
由于地质条件的复杂性,在隧洞施工过程中,可能会遇到各种不同形式的溶洞。溶洞的形式复杂多样,部分溶洞充满孤石、黏土、淤泥等充填物。溶洞的存在,给隧洞的开挖、永久工程质量带来隐患和危害。因此,制定科学、合理、有效的溶洞处理措施,在很大程度上直接影响隧洞的工期及整个工程质量。
Due to the complexity of geological conditions,various forms of karst caves may be encountered during tunnel construction.The forms of karst caves are complex and varied,and some of them are filled with stones,clay,silt and other fillings.The existence of karst tunnel brings hidden dangers and hazards to tunnel excavation and permanent engineering quality.Therefore,formulating scientific,reasonable and effective treatment measures for karst tunnel will directly af fect the construction period and the quality of the whole project to a large extent.
