ABSTRACT
The existing buildings will be affected by rainstorms, floods and other disasters during use. A large amount of rainwater scouring leads to the change in the current situation of the structural soil, which also leads to the change in the service load of the buildings and the overpressure failure of the waterproof structural layer of the soil adjacent structural surface. It will bring irreversible damage to the safety performance and service performance of buildings in use. After the flood, it is of great significance to find out the void of the surrounding soil to restore the safety performance and normal use function of the building. The conventional soil core drilling method is not only time-consuming and laborious, but also needs huge economic support and can only detect the damage to soil point by point. At this time, the advantages of radar wave non-destructive testing technology, which is mostly used for the detection of tunnel lining, highway pavement, water conservancy anti-seepage walls and other projects, are prominent, and it has become the main technical means to detect the damage of soil mass of flood building structure. This paper introduces the relevant principles and achievement analysis methods of radar detection in detail, and introduces the radar detection technology into the field of industrial and civil buildings, which has guiding significance for the post-disaster maintenance and reinforcement of similar projects.
