【摘要】：随着社会的进步、科技的发展、国民经济的不断提高，大型复杂结构建筑的出现已成为必然的趋势，但因为施工过程中、运营期间的种种因素的影响，这些大型复杂结构在施工、运营中发生安全事故的机率相对较高，如何的减少这类事故的发生，提前发出警报信息，做到提前准备，，确保施工顺利进行，确保结构安全使用，结构健康监测显得尤为重要。本文以合肥市渡江战役纪念馆这样一个超高超大悬挑的大型复杂结构为例，首先介绍了结构健康监测的必要性、监测的方法为后面的研究提供了依据。紧接着本文论述了渡江战役纪念馆在施工过程中高支撑架体及其悬挑结构的数值模拟，用ANSYS有限元正装分析法，模拟得出施工过程中悬挑结构高支撑架体及结构本身的关键部位和危险部位，为后面的现场健康监测提供了依据。接下来本文详细论述了渡江战役纪念馆主体悬挑结构在施工过程中高支撑架体及其模板的健康监测系统，并将现场健康监测结果与数值模拟结果进行对比分析，及时提供信息保证悬挑结构施工的安全、顺利的进行，同时也为今后类似的结构施工提供了相关经验。最后就战役纪念馆主体悬挑结构在施工过程中的关键性施工技术进行了介绍，为保证其施工关键技术得以实施，施工健康监测是一项不可缺少的技术措施。
[Abstract]:With the progress of society, the development of science and technology, the continuous improvement of national economy, the emergence of large and complex structural buildings has become an inevitable trend, but because of the influence of various factors during the construction process, during operation, In the construction and operation of these large and complex structures, the probability of safety accidents is relatively high. How to reduce the occurrence of such accidents, issue warning information in advance, prepare ahead of time, ensure smooth construction, and ensure the safe use of the structure, Structural health monitoring is particularly important. Taking Hefei Dujiang campaign Memorial Hall as an example, this paper first introduces the necessity of structural health monitoring, and the monitoring method provides a basis for further research. Then, this paper discusses the numerical simulation of the elevated support and its overhanging structure in the construction process of the Memorial Hall of the Battle of the Cross River, using the ANSYS finite element orthographic analysis method. The simulation results show that the high brace and the key and dangerous parts of the structure itself in the construction process provide the basis for the on-the-spot health monitoring of the cantilever structure. Next, this paper discusses in detail the health monitoring system of the high support and its formwork in the construction process of the main overhanging structure of the Memorial Hall of the Battle of the Dujiang River, and compares the results of the on-site health monitoring with the results of numerical simulation. To provide timely information to ensure the safety and smooth construction of overhanging structure, and to provide relevant experience for similar structure construction in the future. Finally, the key construction techniques of the main overhanging structure of the campaign memorial are introduced. In order to ensure the implementation of the key construction techniques, the construction health monitoring is an indispensable technical measure.
