［摘要］高空飞翔游乐设施的地基基础作为构筑物承载的核心部分，合理设计尤显重要，直接影响到整个结构运营的安全性、稳定性和耐久性。首先根据相关规范及其构筑物的高度确定基础的埋置深度，其次根据地表以上结构传递的荷载特点及其大小确定基础的形状和尺寸，最后采用FLAC3D软件建模，分析最不利工况下地基的承载力及基础的沉降，验证地基基础设计的正确性。特别是在处理施加在地基基础上的荷载时，将上部结构传递的力矩转换成分布力，其中拉力以及水平剪力作用在地脚螺栓上，压力作用在钢筋混凝土上。计算结果表明基础设计满足规范要求。

Abstract:The foundation is a core part of a high altitude flying recreation facility, so its reasonable design is particularly important to impact the security, stability and durability of the entire structure operation. First, the embedment depth of foundation was determined according to related codes and the height of the structure. Secondly, the shape and size of the foundation were determined according to the characteristics and sizes of loading transferred in the structure upper the soil surface. Finally, FLAC3D software was used to establish model to analyze the base bearing capacity and foundation settlement under the most unfavorable working condition, to verify the correctness of foundation design. Especially in treating loadings on foundation, the torque distribution force transferred by the superstructure was converted into distributive forces, of which tensile force and horizontal shear force acted on the anchor bolt of foundation and the compression force acted on reinforced concrete. Calculation results show that foundation design fulfill requirements of codes.

Keywords:recreation facility; design and calculation of foundation; base bearing capacity; foundation settlement
