为研究深水基础围护技术，以盘海特大桥480#主墩为研究对象，采用钢管桩与钢板桩联合形成组合桩，建立新型深水基础围护支撑体系，提出具体施工方法。根据该围护体系特点，进行基底流砂应急处理，提出运用旋喷桩进行整体帷幕与局部重点治理相结合的处治方法。经实践证明：该新型深水基础围护体系能够节时、低耗、及时、有效的解决高水位、高压力对基础工程建设的不利影响，为以后同类工程提供有力的借鉴。

In order to study the enclosure technique for deep water foundation,taking 480# main pier in Panhai su-per bridge as research object,the composite pile by combining steel pipe pile with steel sheet pile was applied. A new type of enclosure bracing system for deep water foundation was established,and the concrete construction method was put forward. According to the characteristics of this enclosure system,the emergency treatment for quicksand on basement was presented with the treatment method of the whole curtain combining with local focus by rotary jet pile. The practice proved that the new enclosure system is time-saving,energy-saving,and can solve the adverse effect caused by high water level and heavy pressure in foundation engineering construction timely and ef-fectively. It provides strong reference for similar projects in the future.
