摘要
主要介绍了南水北调中线一期穿黄工程,在黄河滩地软弱地层(地层为砂层)修建超深竖井(竖井深度50.5m)的工程实例。通过合理的设计,克服了地下水位高;地质条件复杂等因素的制约。文中详细阐述了修建超深竖井的施工技术与施工工艺。
This paper introduces a case of extra- deep shaft （50.5m deep） project in soft ground （sand stratum ） of Yellow River Overbank, part of Yellow River Crossing Project for South - North Water Transfer Middle Line Project Phase I, describes the extra - deep shaft eonstruetion technology and process of overcoming the unfavorable faetors such as high ground water level and poor geology via proper design.
