Buoyancy compensation type combined foundation and construction method
The invention relates to a buoyancy compensation type combined foundation and construction method. The buoyancy compensation type combined foundation comprises a plurality of supporting piles, a bearing platform, a main buoyancy tank, a conversion layer and a bottom sealing layer. The bottom sealing layer is arranged at the bottom of the bearing platform. The supporting piles form pile groups, andthe top ends of the pile groups penetrate the bottom sealing layer and are connected with the bearing platform. The main buoyancy tank is arranged on the bearing platform. The conversion layer is arranged on the main buoyancy tank and used for bearing a column body so as to transmit the upper structure load to the main buoyancy tank. According to the buoyancy compensation type combined foundationand construction method, the main buoyancy tank is large in buoyancy, the vertical load effect transmitted into the supporting piles is greatly reduced, the design of the supporting piles is controlled by the section strength of the pile bodies, and the influence of a deep soft covering layer on pile foundation design is reduced. The buoyancy compensation type combined foundation has the advantages of being small in pile foundation scale, reasonable in economic index and the like. The group piles formed by the supporting piles mainly bear vertical force, the main buoyancy tank bears most of horizontal force and bending moment transmitted by the upper portion, the free pile length portion of a traditional pile foundation is replaced, the horizontal load bearing capacity of the foundation is improved, and the influence of water depth, local scouring and stormy waves on foundation stress can be reduced.
本申请涉及一种浮力补偿式组合基础及施工方法，包括多个支承桩、承台、主浮箱、转换层和封底层；封底层设于承台底部，支承桩形成群桩，群桩顶端穿入封底层并与承台连接；主浮箱设于所述承台上；转换层设于主浮箱上，并用于承载柱体，以将上部结构荷载传递至主浮箱。本申请实施例提供的主浮箱所受浮力大，大大减少了传入支承桩的竖向荷载作用，支承桩的设计由桩身截面强度控制，降低了深厚软弱覆盖层对桩基设计的影响，具有桩基规模小，经济指标合理等优点。支承桩形成的群桩主要承担竖向力，主浮箱承担上部传递的大部分水平力及弯矩，替代传统桩基础自由桩长部分，提高了基础承受水平荷载的能力，可减小水深、局部冲刷、风浪对基础受力的影响。
