法门寺合十舍利塔震后裂缝处理技术研究
|
摘要
法门寺合十舍利塔工程是"5·12"汶川大地震发生时在建的陕西省重点工程,通过对该工程在汶川地震后的震害调研、地震现场考察,收集了大量有关该建筑结构震害资料,介绍了受汶川地震影响的法门寺合十舍利塔的震害情况,对裂缝产生的原因作了初步分析,并根据具体破坏特征提出表面封闭、表面扩大封闭、压力灌浆、补强钢带等相应处理(加固)措施.
The project of the Palms Together Pagoda in the Famen Temple are the main projects in Shaanxi Province.It was under construction when Wenchuan earthquakes occurred.The large amount of data were collected about the building structure damage level based on the damaged buildings and scene investigation after earthquakes.These data reflected the earthquake effect on the Palms Together Pagoda in Famen Temple.And causes of the damage are analyzed and some measures such as closed surface and pressure grouting and steel reinforcement are provided.The treatment technology discussed in the article would be valuable for other similar projects.
