[提要] 介紹了合肥CBD中央廣場工程超長超寬大底盤多塔復(fù)雜結(jié)構(gòu)的整體設(shè)計(jì)、分析與對策。通過基礎(chǔ)方
案選定、上部結(jié)構(gòu)抗震性能分析及大底盤超長結(jié)構(gòu)不設(shè)溫度縫的可行性研究,論證了該工程五棟高層塔樓通過大底盤相連的結(jié)構(gòu)設(shè)計(jì)是可行和安全可靠的??晒╊愃乒こ虆⒖?。
[關(guān)鍵詞] 超長超寬結(jié)構(gòu) 多塔 高層建筑 人工挖孔樁Taking the central palaza in Hefei CBD as an example, the integral design of a kind of multi-tower tall building with enlarged base is introduced.The foundation project is chosen,the seismic analysis of the upper structure is carried out, and the calculation of temperature stresses and crack-leak control scheme of the superlong and superwide structure are also made.Then the feasibility research on the complicated structure without contraction joints is discussed.
Keywords: superlong and superwide structure; enlarged base; multi-tower; tall buildings; manual bore cast-in-place pile參 考 文 獻(xiàn)
