摘　　要：建筑承台承受着上部结构墙柱传来的竖向力,同时亦受到底板传来的浮力,是复杂的竖向力与水浮力共同作用的传力构件,起到将上部结构与桩基础的外力进行平衡的关键传力作用。目前,如何考虑水浮力与竖向力的复合作用并对承台进行设计,在工程界还未有完整的理论依据。本文将就此展开研究分析,为承台考虑竖向力及水浮力共同作用作出理论分析及方法探讨。Pile cap bearing vertical force from the wall column of upper structure, and buoyant force from the base plate, is a complex connecting component under vertical force and water buoyant force. It plays a key role in transferring forces to balance the external forces of upper structure and pile foundation. Nowadays, there is no complete theoretical base in engineering field, for the design of pile cap considering combined action of water buoyant force and vertical force. The paper will carry out research and analysis on this issue, and the theoretical analysis and method discussion will be made on design of pile cap considering combined action of vertical force and water buoyant force.
