摘　　要：主楼周边地下室分布影响主楼地基附加应力分布。地下室非对称分布会引起主楼较大荷载偏心,从而导致主楼沉降不均匀,甚至倾斜超标危及建筑安全。结合具体工程实例,分析非对称分布地下室对主楼倾斜的严重影响,以引起方案设计的重视,避免类似事故的重复发生。Basement distribution around a main building affects the additional stress distribution of the main building foundation.The asymmetric distribution of basements will cause large load eccentricity in main buildings,resulting in uneven settlement of main building and even excessive tilting,which will endanger building safety.This paper analyzes the serious influence of asymmetrically-distributing basements on the tilting of main building based on specific engineering cases,so as to provide a reference for scheme design and avoid the recurrence of similar accidents.

关 键 词：地基 地下室 非对称建筑 偏心荷载 不均匀沉降 楼体倾斜
