［摘要］月壇金融中心由5棟高層塔樓、1棟體育訓(xùn)練館及商業(yè)裙房組成。5棟塔樓地上18～23層，采用鋼梁矩形鋼管混凝土柱框架-鋼筋混凝土核心筒混合結(jié)構(gòu)體系。體育訓(xùn)練館地上1層，裙房地上4層。整個(gè)建筑物地下部分連成一體，共5層，置于同一個(gè)筏形基礎(chǔ)上，基底埋深約27m。高層塔樓與低層裙樓、高層塔樓與純地下車庫之間的荷載差異大，沉降控制難度大。此外，本項(xiàng)目還存在地下水位高，抗浮設(shè)防水位的基底水頭達(dá)21m，抗浮設(shè)計(jì)有一定難度。介紹了結(jié)構(gòu)基本情況、地基基礎(chǔ)設(shè)計(jì)、沉降分析以及抗浮設(shè)計(jì)，特別是多個(gè)高層塔樓、多層裙房和純地下室連成一體且基礎(chǔ)不設(shè)永久沉降縫時(shí)的設(shè)計(jì)理念、設(shè)計(jì)過程和沉降觀測(cè)數(shù)據(jù)分析，以期對(duì)類似項(xiàng)目的基礎(chǔ)設(shè)計(jì)和沉降控制提供參考。

Abstract:Yuetan Financial Center consists of 5 high-rise towers,1 sports training hall and a commercial podium. The 5 towers have 18 to 23 floors above the ground, and mixed structural system composed of steel beam rectangular concrete-filled steel tube column frame and reinforced concrete core tube was adopted. The sports training hall has one floor above the ground and the podium has four floors above the ground. The underground part of the whole building is connected into a whole, a total of 5 floors, placed on the same raft-shaped foundation with a depth of 27m below the ground. The load difference between high-rise towers and multi-story podium, high-rise towers and pure underground garage is large, and therefore the settlement control is difficult. In addition, due to the high groundwater level in the project, the base water head of the anti-floating waterproof level reaches 21m, which makes anti-floating design be difficult. The design process including the structure information, foundation design, settlement analysis and anti-floating design, especially the design concept that multiple high-rise towers, multi-story podium and pure basement are connected into a whole without any permanent settlement joints, and as well as analysis on the settlement observation data were introduced, so as to provide reference for foundation design and settlement control of similar projects.

Keywords:Yuetan Financial Center； high-rise building; structural design; foundation design; anti-floating anchor； differential settlement
