[摘要]榆林市体育中心新建体育场基础采用封闭式环形基础梁体系+钻孔灌注桩+钢筋混凝土拱墩的形式。通过对本工程的基础进行设计,探讨在风积砂的地质条件下,依靠基础梁体系自身强度及刚度、辅以桩身水平抗力及基础周边土体的抵抗力等来承受上部大跨度拱结构产生的巨大水平推力作用和控制基础的变形量,以减少对上部结构的不利影响。

Abstract: The foundation of new stadium of Yulin City Sports Center adopts the structural system of enclosed circular foundation beams, bored piles and reinforced concrete arch. Through the foundation design of the example project, it was researched how to counterbalance the huge horizontal force from the above large-span arch structure and control foundation deformation with the help of strength and stiffness of the foundation beams, horizontal resistant force of the pile and soil resistance force around the foundation on the geological condition of aeolian sand to avoid great detrimental effect on the super structure.
Keywords: enclosed circular foundation beam; sand ground; horizontal displacement control; horizontal bearing capacity
