Abstract: The foundation supports the superstructure, and the stability of the foundation is closely related to the stability of the superstructure. As a hidden project, it is difficult to find out whether the foundation is damaged in its service life. Once the damage occurred, the consequences might be very serious. Currently, most appraisal agencies estimate the degree of potential hazards of the building foundations by observing the cracks, inclination or deformation of the superstructure. In special cases, the foundation might be exposed to estimate the degree of damage. However, to observe the damage of the foundation throughout the deformation of the superstructure can only be found after severe deformation has occurred. Further, the location of the problematic soil stratum and the degree of damage of the foundation cannot be directly determined. This paper presents a method of indirect identification of foundation damage-geophysical investigation method, and verifies the reliability of this method through exploration method.
