摘　　要：通过合理配置水下不离析水泥砂浆,利用暗基床四周土体和已安沉箱所形成的相对密封环境,采用在沉箱上预埋灌浆管及搭设施工平台,以及选择合适的灌浆施工参数等技术措施,海中独立墩沉箱抛石基床的水下灌浆工艺在青岛港30万吨级原油码头建设中得以应用。压力灌浆可以实现抛石基床的整体密实,基本消除后期沉降,对类似工程具有参考意义。The underwater grouting technology of rubble-mound of a single gravity pier is applied successfully in Qingdao 300 000 DWT crude oil wharf＇s construction by the technical measures such as proper configuration of sanded cement grouting without occurrence of segregation using relatively sealed condition formed by soils around closed bedding and caisson installed, use of built-in grouting pipe and construction platform on caisson, proper construction parameters, etc. The rubble-mound foundation can be compacted and its settlement after construction can almost be avoided by underwater grouting, which provide reference for other similar projects.
