石佛像减隔震保护研究
|
摘要
为研究预防性保护—减隔震技术在地面浮放石像文物中的应用,基于规范公式首先确定了佛像的隔震系数和支座刚度范围,进而采用时程分析程序对初选的减隔震支座进行了数值仿真验证,研究了高宽比为5.6的石佛像采用减隔震支座的可行性问题。研究结果表明:处于高烈度区浮放于地面的具有较大高宽比的石佛像文物的抗震性能存有隐患,科学合理的减隔震支座用于佛像等结构物可取得显著的减震效果。本研究所做石佛像减隔震设计及分析验证思路对类似工程有借鉴意义。
The feasibility of isolation protection of a stone Buddha with a height-to-width ratio of 5. 6 under seismic condition is discussed in this paper. First,based on standard formulas,the isolation coefficient and bearing stiffness range for the Buddha were determined under seismic conditions. The primary isolation bearings vs. time was studied by numerical simulation. It can be concluded that sufficient attention needs to be paid to historical relics such as an unfixed Buddha with large height-to-width ratio in the high intensity region because of the existence of hidden dangers of their seismic performance. Furthermore,isolation bearings can be utilized with structures having large height-to-width ratios,such as stone Buddha,in order to produce a significant isolation effect. These ideas,have reference value for similar projects.
