在密集的建筑群中,建造高层建筑,补偿基础地一种合适的基础形式。埋深在10m左右的箱形补偿基础的基底反力分布是人们关心的问题。通过同济大学图书馆扩建工程的箱底反力的量测,与理论值比较可知,地下连续墙不但起到围护作用,还可起到减小箱形基础整体弯矩的作用。 In dense buildings, high-rise buildings are constructed to compensate for a suitable basic form of the foundation. The base-reaction distribution of the box-shaped compensation foundation with a depth of about 10m is a concern. Through the measurement of the reaction at the bottom of Tongji University Library’s expansion project, compared with the theoretical value, it can be known that the underground continuous wall not only plays a role of enclosing, but also can reduce the overall bending moment of the box-shaped foundation.
