(中國建筑西北設計研究院,西安710003)[提要]在西安地區(qū),建筑物的計算沉降和實測沉降往往有較大的差異,根據計算值,高層建筑和多層裙房的基礎之間必須設置沉降縫。通過對五個基礎形式不同的工程實例的實測沉降進行分析和整理,闡述了高層建筑帶多層裙房或僅帶1~2層地下室時基礎地下室連為整體不設沉降縫的可行性和可靠性,可為今后類似地基基礎設計提供借鑒。[關鍵詞]高層建筑;裙房;基礎;地下室;沉降縫;差異沉降Settlement Observation and Analysis on Intensity Foundation of High-rise Building and Podium/Shen Licao,Zheng Yongqiang,Zhong Chongmin,Lu Ning(China Northwest Building Design Research Institute,Xi’an 710003,China)Abstract:There is much difference between the calculation and observation settlement of building in Xi"an.According to the calculation result,the settlement joint must be set between the high-rise main building and the multi layer podium.Based on the settlement observation data of five high-rise buildings with different foundation styles,the feasibility and reliability of no settlement joints when the high-rise building has multi-layer podium or 1~2 layer basement are discussedKeywords:high-rise building; podium; foundation; basement; settlement joint; differential settlement
