地下室结构设计非常复杂,其设计诸多技术问题,包括地基承载力问题、变形问题、抗浮问题、不均匀沉降问题,或是结构超长、基础形式选择、计算方法、人防设计等方面问题。现代高层建筑因技术经济水平的发展,其大都设有大底盘地下室,一般都是1-4层,且面积约占整个建筑面积的15%-35%。本文分析了高层建筑群共用大底盘地下室结构设计,并提出实用性应用策略。 Basement structure design is very complex, and its design of many technical issues, including the foundation bearing capacity problems, deformation problems, anti-floating problems, uneven settlement, or the structure of long, basic forms of choice, calculation methods, civil air defense design and other aspects. Due to the technical and economic development of modern high-rise buildings, most of them have large chassis basements, generally 1-4 floors, and occupy an area of ​​about 15% -35% of the total construction area. This article analyzes the high-rise buildings sharing large chassis basement structure design, and put forward practical application strategies.
