针对结构病害处理学科对技术概念的分类繁乱的现象，提出了纠倾技术分技术途径、技术原理、施工方法三个层次。按照技术途径，纠倾技术分迫降和顶升两种；按技术原理，迫降技术有应力解除法、应力附加法、地基刚度软化法、卸荷法等四种；顶升技术又有截断顶升和膨胀顶升两种，最后对纠倾技术的分类进行了汇总，对结构纠倾技术的层次进行了系统化，以方便对照原因对结构进行纠倾处理。

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.
