Description

technical field [0001] The invention belongs to the technical field of building stress distribution testing, and in particular relates to a testing system and method for reflecting parameter of building stress distribution. Background technique [0002] Electrical resistance tomography has the advantages of being non-invasive and radiation-free. Especially in modern industrial detection, geological exploration and other aspects have such a wide range of application prospects and advantages. Due to the uneven distribution of stress in the process of design and use of buildings, it will bring major safety hazards. Existing building stress testing products are costly, and testing devices need to be buried in buildings, which is inconvenient for mobile monitoring and popularization. For example, when the sound vibration and structural stress change sensors of reinforced concrete structures are used to detect the building stress distribution, the stress sensing unit needs to be...
