【摘要】：近年来,随着国家大剧院、国家体育场“鸟巢”、CCTV新台址、广州歌剧院以及广州图书馆等一批大型复杂建筑结构建设的兴起,以及施工过程中日益增多的安全事故,建筑施工过程中的安全问题越来越受到关注。因此,对大型复杂高层建筑进行施工仿真分析和施工监测对保障其施工过程的安全是很有必要的。广东兴业国际仓储科研主楼结构建筑造型独特,结构形式新颖。本文以该结构为工程实例,对其施工过程中的施工监测进行了深入研究,具体工作内容如下： 1、在广泛查阅相关文献的基础上,回顾了高层钢框架-混凝土核心筒这一混合结构的工程应用状况,简单介绍了混合结构的受力特点、施工特点及施工期间的时变特性。 2、探讨了复杂高层混合结构施工监测原理、方法以及施工过程力学理论与实现方法。 3、利用状态变量叠加法,采用大型有限元软件Midas/Gen对广东兴业国际仓储科研主楼结构安装过程进行仿真分析,分析出不同施工工况对结构的影响,并以此科学合理地指导施工监测。 4、介绍了该结构整个施工过程及施工监测过程,并将实测的应力、位移数据与仿真计算结果进行对比分析,保障了施工的安全。并对监测中误差的产生原因进行讨论分析。本文以广东兴业国际仓储科研主楼为背景,对复杂高层混合结构施工监测进行了研究,得出只有把施工仿真分析与施工监测有机结合起来,才能更有效地保障复杂高层混合结构施工过程中的安全。
[Abstract]:In recent years, with the rise of the National Grand Theater, the National Stadium "Bird's Nest" and the new site of CCTV, the rise of the Guangzhou Opera House and the Guangzhou Library, and the increasing number of safety accidents in the construction process, More and more attention has been paid to the safety problems in the construction process. Therefore, it is necessary to carry out construction simulation analysis and construction monitoring for large and complex high-rise buildings to ensure the safety of their construction process. Guangdong Xingye International warehousing and Research Building has unique structure and novel structure. Taking the structure as an engineering example, this paper makes a deep study on the construction monitoring in the construction process. The specific work contents are as follows: 1. On the basis of extensive reference to relevant documents, the engineering application of the high-rise steel frame-concrete core-tube composite structure is reviewed, and the mechanical characteristics, construction characteristics and time-varying characteristics of the composite structure during construction are briefly introduced. 2. The construction monitoring principle, method, mechanics theory and realization method of complex high-rise mixed structure are discussed. 3. By using the superposition method of state variables and large scale finite element software Midas/Gen, the structural installation process of Guangdong Xingye International Warehouse and Research main Building is simulated and analyzed, and the influence of different construction conditions on the structure is analyzed. And with this scientific and reasonable guidance construction monitoring. 4. The whole construction process and the construction monitoring process of the structure are introduced, and the measured stress and displacement data are compared with the simulation results to ensure the safety of the construction. The causes of errors in monitoring are discussed and analyzed. Based on the background of Guangdong Xingye International Warehouse and Research Building, this paper studies the construction monitoring of complex high-rise mixed structure, and draws the conclusion that only the construction simulation analysis and construction monitoring can be combined organically. In order to ensure the safety of the complex high-rise hybrid structure more effectively.
