Abstract:Research purposes:The 7.1 magnitude earthquake took place in Yushu on April 14,2010 and it caused collapse of many resident houses and almost razed the Jiegu Town to the ground.For remembering this historic event,the damaged Gesaer Hotel was determined as the earthquake ruins,so it was necessary to protect and reinforce the hotel.The design of the reinforcement scheme was researched and the reinforcement construction process of the hotel was summarized for the purpose of providing the reference to the similar works.
Research conclusions: Based on research on the reinforcement scheme,the design and construction of the Gesaer Hotel,the following key points of reinforcing and protecting the earthquake ruins are concluded: (1) The in - site investigation and assessment should be conducted in detail and the construction procedure should be arranged reasonably before reinforcing.The engineering of avoiding the building toppling down should be conducted before conducting the reinforcement engineering of the building structure.(2) Based on the latest actual in - site investigation data and knowledge,the reinforcement programme should be adjusted and optimized for guaranteeing the construction security and effectively protecting the ruins.(3) During and after the reinforcement engineering,the monitoring spots should be installed in the major ports of the building,and the security of the building and person can be guaranteed and the reinforcement effect can be known by dynamic monitoring the deformation change.
