［摘要］超高層建筑對地基承載力的要求較一般高層建筑明顯高出很多，目前，勘察報告提供的深層砂土、碎石土地基承載力偏低，無法滿足超高層建筑對地基承載力和變形的要求，因此對深層地基承載力的試驗研究越發(fā)重要。通過現(xiàn)場靜載試驗及重型動力觸探試驗對深層地基土承載力的確定方法進行研究，結(jié)合現(xiàn)場試驗結(jié)果和已有超高層建筑選用天然地基得到的沉降資料，得出砂土、碎石土地基承載特性和地基承載力特征值。研究結(jié)果可供深層砂土、碎石土地基上的超高層建筑地基基礎(chǔ)設(shè)計參考。

Abstract:The requirements of the foundation bearing capacity for super high-rise buildings are obviously higher than that of ordinary high-rise buildings. At present, the bearing capacity of deep sand and gravel foundation offered by geotechnical investigation report is usually lower than its actual condition, and it can not satisfy the requirement of bearing capacity and deformation for super high-rise building. Therefore, it′s important to study the foundation bearing capacity of deep layer. The method to determine the bearing capacity of foundation soil in deep layer was studied through the field static load test and heavy dynamic penetration test, and the foundation bearing capacity and the bearing capacity characteristic value of the sand and gravel foundation were obtained based on the field test results and the settlement data of the existing super high-rise building adopting natural foundation. The study results can provide references to the foundation design of super high-rise building on deep layer sand and gravel base.
Keywords:super high-rise building; foundation bearing capacity; static load test
