Research on key technology of jacking rectification with separation of vertical components of high-rise buildings
In order to reveal the internal mechanism of jacking rectification technology with separation of vertical components of high-rise buildings,the theoretical simulation method of jacking system was given,and the influence of three factors on the internal force of the structure was studied from the layout of jacks,jacking control mode and jacking error.By comparing the results of internal forces under the influence of various factors,the key technologies in the design and construction of jacking rectification with separation of wall and column were summarized.The results show that the arrangement of one-way double jacks is not desirable in the process of separation jacking.The double control jacking mode of ＂force first,displacement second＂ is more suitable for practical engineering.Small error in jacking may cause great additional internal force,which should be avoided through theoretical analysis and construction control.
