玉树地震遗址补强加固方法
|
摘要
研究目的:2010年4月14日,玉树发生了7.1级强烈地震。居民住房大量倒塌,重灾区结古镇几乎夷为平地。为纪念这特定的历史事件,受地震破坏的玉树格萨尔宾馆被定位为地震遗址加以保护,需对其进行抢险加固,通过对格萨尔宾馆加固方案设计研究和施工的总结,为今后此类项目提供借鉴和参考。研究结论:通过对格萨尔宾馆加固方案研究、设计和施工,总结出地震遗址加固保护工作的要点为:在加固工程施工前,首先对现场仔细调查评估,合理安排工序。先施工防止建筑物倾覆的工程,后实施对建筑物结构补强加固的工程;要根据对现场最新的实际调查和认识,要不断对加固设计进行调整和优化,以有效地做好施工安全和遗址的保护工作;加固施工期间和完成后,对建筑物主要部位设置监测点,通过动态监测,确切掌握建筑物的变形变化情况,以保证建筑物和施工人员的安和评价加固保护效果。
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.
