摘　　要：通过对区域地下水浮力作用机理的认识,在研究异常高地下水位条件下特定区域的成层地基土与结构基础静力相互作用特性的基础上,研究了某结构由于地下水位异常升高导致上部结构的破坏的特性,得到了成层地基土、基础与上部结构相互作用机理、地下水浮力简化计算方法及其相关破坏机理,该结论可为基础和上部结构设计、既有建筑物因地下水浮力异常升高导致上部结构破坏的演化过程和加固技术研究提供借鉴。Based on the mechanism understanding of the buoyancy effect of the regional groundwater,on the base study about the static features of the interaction between a layered foundation soil and the structural basis on an abnormally high water level conditions of a particular region,the study of the destruction properties of the upper structure were established due to the elevated underground water level,by the above study the interaction mechanism among the layered subsoil, the foundation and the upper structure; the simplified calculation method of the groundwater buoyancy and the characteristics of the destruction of the upper structure has been gotten. This conclusion can provide the basis for the design of the foundation and upper structure of the building,the understanding of the damage elevation of the upper structure of the existing building which due to the abnormal in-crease of ground water buoyancy and the research of the reinforcement technology.
