Abstract: A five layers leaned teaching building based on the raft foundation was forced to settle down for rectifying leaned structure by comprehensively using stress relieving method, stress additional method, ground stiffness softening method on basis of the indoor forced settlement for rectifying leaned structure experimental research achievements, the leaned building smoothly back leans with the movement joint and the leaning rate reaching the technical requirements of the regulations. A successful model to deal with the construction plague was presented.
Keywords: structure plague; rectification; stress relieving method; stress additional method; stiffness softening method
