[摘要]榆林市體育中心新建體育場(chǎng)基礎(chǔ)采用封閉式環(huán)形基礎(chǔ)梁體系+鉆孔灌注樁+鋼筋混凝土拱墩的形式。通過對(duì)本工程的基礎(chǔ)進(jìn)行設(shè)計(jì),探討在風(fēng)積砂的地質(zhì)條件下,依靠基礎(chǔ)梁體系自身強(qiáng)度及剛度、輔以樁身水平抗力及基礎(chǔ)周邊土體的抵抗力等來承受上部大跨度拱結(jié)構(gòu)產(chǎn)生的巨大水平推力作用和控制基礎(chǔ)的變形量,以減少對(duì)上部結(jié)構(gòu)的不利影響。

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
