Measurement method for building surface micro-deformation

The invention relates to a building deformation measurement technology, in particular to a method for measuring micro-deformation of a building surface, which comprises the following steps of: burying piezoelectric sensors which are arranged at intervals at the same horizontal height of a building, and forming a piezoelectric sensing network by a plurality of piezoelectric sensors which are positioned at the same horizontal height, signals of the piezoelectric sensors are transmitted to the signal processor, and data are analyzed and processed through the signal processor to obtain the deformation condition of the surface of the building. According to the invention, a plurality of piezoelectric sensors which are arranged at intervals are arranged at the same horizontal height of the building to form a piezoelectric sensing network, so that the influence of an external load on the building can be monitored in real time, and the deformation condition with a time sequence characteristic can be further judged thr
