摘要(Abstract)：
利用压力平衡原理 ,提出了钢护筒埋设最佳值的确定方法 ;据室内实验结果 ,给出了海水泥浆的配方和维护方法 ;结合工程实际 ,总结出海上施工泥浆循环系统的合理布设和水下混凝土灌注等关键技术。所述技术在港口、码头、桥梁和海洋桩基施工中具有实际应用价值
Based on the theories of pressure equilibrium,this paper puts forward the method of determining optimal depth of steel protective case.Combining with the results of indoor experiment,the composition and support of seawater drilling fluid are raised.Combining with the engineering,the reasonable layout of drilling fluid circulation system on the sea and the underwater ferroconcrete are summarized.The above mentioned techniques have the actual application on ocean foundation in the port,wharf and bridge.
