摘要: 地基基础支撑着上部结构,地基基础的稳定关乎着上部结构的稳定;地基基础作为隐蔽工程,日常很难发现其是否破坏,一旦发现破坏,后果很严重。目前多数鉴定单位都是通过观测房屋上部结构的裂缝、倾斜或变形来判断地基基础的危险程度,特殊情况采用开挖基础的方式来判断其损坏程度。通过上部结构变形观测来判定地基基础的损坏,必须在已出现一定变形后才能发现问题,而且不能直接判定产生问题地层位置及基础的损坏程度和范围;在此基础上,提出一种间接鉴定地基基础损坏的方法——物探方法,并通过勘探方法来验证此方法的可靠性。

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.
