摘要
西藏布达拉宫建筑群是著名的世界文化遗产,西印经院是该古建筑群的重要组成部分,为保护布达拉宫建筑群的完整性,对西印经院的稳定性开展研究。在进行详细现场调查和工程地质勘察工作的基础上,分析结构破坏的特征和变形力学机制。应用三维模拟技术,分析西印经院在结构荷载作用下的差异性沉降规律,研究西印经院在自重和地震组合作用下的破坏机制,验证对西印经院变形破坏力学机制分析的准确性。根据上述工作确定对结构稳定性进行定性分区评价的原则,研究结果可为该文物建筑工程的防护对策提供科学依据。
The Potala Palace is one of the most famous cultural heritages in the world. The West Scripture Printing Hall is an important part of the Potala Palace. This paper focuses on describing the investigation on the stability of the West Scripture Printing Hall. Base on the detailed measured data and engineering geological exploration, the characteristics and mechanisms of deformation of the West Scripture Printing Hall have been analyzed. The three-dimensional simulation technique has been applied to analyze the differential subsidence pattern of the West Scripture Printing Hall under the structural load. Furthermore, the damage mechanisms of the structure under the gravity and earthquake load have been achieved. The principle of qualitative zoning assessment to the stability of the structure has also been confirmed. The results of analysis show that the behaviors of the damage and deformation characteristics of the West Scripture Printing Hall under the seismic load and gravity are proved to be very helpful to structural protection analysis and damage control approaches selection.
