Classification of the technical concept in structural defect treatment is very complicated and disorganized. We proposed that rectification measures of tilted structures can be classified into three stages, which were technical approaches, technical principles, and construction methods. Based on technical approaches, rectification measures were divided into forced settlement and liftup technologies. The former included stress relief, stress addition, foundation stiffness softening, and unloading methods based on technical principles. The latter included truncation liftup and expansion liftup. At last, we summed up different sorts of rectification measures and systemized sorting administrative levels.
