［摘要］北京地區(qū)某項(xiàng)目的基礎(chǔ)設(shè)計(jì)中，針對(duì)不同類(lèi)型的建筑結(jié)構(gòu)采取了不同的優(yōu)化設(shè)計(jì)方法。對(duì)于地基持力層的承載力特征值略低于主樓基底壓力的情況，采用加強(qiáng)主樓和裙房或純地下室的整體性、擴(kuò)散主樓荷載到裙房或地下室區(qū)域的優(yōu)化設(shè)計(jì)方法。對(duì)于帶裙樓建筑的高層建筑采用變剛度調(diào)平設(shè)計(jì)方法。地基變形計(jì)算和沉降觀測(cè)結(jié)果表明該項(xiàng)目基礎(chǔ)設(shè)計(jì)優(yōu)化取得了較好的結(jié)果。

Abstract: In the foundation design for a project in Beijing, different optimal design methods were adopted for different building structure types. For the condition that characteristic value of bearing capacity of foundation bearing layer is less than gravity of building, structural optimization design method was used to strengthen the structure integrity and diffuse the gravity to the podium or basement. Foundation stiffness optimization design method to reduce differential settlement was applied in the high-rise buildings with podiums. Results of calculation of foundation deformation and settlement observation show that the optimal design is reasonable and feasible.

Keywords: optimization design of the foundation; strengthen the structure integrity; foundation stiffness optimization design method to reduce differential settlement; difference settlement; tilt; settlement observation
