摘　　要：底板土模成型斜柱板式基础下层底板采用土模成型,上平面边缘采用45°坡角设计,增加了基础埋置深度,从而增强其抗拔承载力并且减小混凝土量。通过不同地质条件的底板土模成型斜柱板式基础的真型试验,验证基础设计计算理论,分析基础承载特性、规律和工程应用的可行性,总结出相应的施工工艺。The bottom pad of a new type of inclined column concrete foundation is formed by ground formwork with the upper surface of the column sloping 45 degrees,which increases the embedding depth of the foundation,consequently increasing the uplift resistance and reducing concrete volume.Full-scale tests were performed on this type foundation with different geological conditions to verify the design theory,and to analyze the bearing characteristics of the foundation and the feasibility of its engineering application.Suitable construction techniques are also summarized.
