烟台港西港池二期工程突堤北侧东半部码头采用了沉箱重力式结构,其地基为承载能力较低的亚粘土、亚沙土,并间夹有淤泥质亚粘土。该工程由第一航务工程设计院设计。设计采用了深层水泥拌合法(简称CDM工法——Cement Deep Mixing Method)。加固软土地基,其加固深度为7～10米。这是我国继天津新港东突堤北侧重力式码头之后,又一个在软土地基上建设的沉箱重力式码头。 烟台港此次采用本工法实施是完全由我国的技术人员设计施工,用我国自行开发的水上深层水泥拌合船组,用我国自行研制的海上定位系统、自行研究的微机软件,完全由我局建港工人、船员进行操作的全新尝试。而今,工程已进展过半,施工情况正常,一次成功地达到了刚刚开发的船机设备所预期的技 The east half of the jetty on the north side of the jetty in West Harbor Terrace Phase II of Yantai Port adopts a caisson gravity structure. The foundation is a loam with low bearing capacity, sandy soil and muddy loam. The project by the first flight Engineering Design Institute. Design uses a deep cement mixing method (referred to as CDM - Method Deep Mixing Method). Reinforcement of soft soil foundation, the reinforcement depth of 7 to 10 meters. This is our country following the Tianjin Xingang east jetty north of the gravity wharf, and another in the soft ground caisson gravity wharf. The implementation of this method by Yantai Port is completely designed and constructed by our technicians. With our self-developed submerged deep-sea cement mixing vessel group, our self-developed marine positioning system and the computer software researched by ourselves are completely owned by the Ministry of Science and Technology Hong Kong workers, crew members to operate a new attempt. Today, the project has progressed more than half, the construction is normal, once successfully reached the just-developed technology of ship equipment expected
