Method for detecting lowering of foundation of building, involves determining gravitational forces of foundation based on signals from acceleration sensor attached to foundation in fastening position, at different points of time

摘要

The method involves attaching (10) an electronic acceleration sensor on a foundation of building in fastening position. The gravitational forces of the foundation are determined (12,14) based on signals from the acceleration sensor at different points of time. The difference between gravitational forces is determined (16) and dynamic fluctuation of the foundation is detected.
