| 摘 要： | 北京地铁大兴线某车站在施工完成1年后,其邻近建筑物墙体与楼板出现不同程度的裂缝.为评定该建筑物结构的安全性,以现场检测统计数据为依据,采用结构力学中的位移法,运用ABAQUS有限元软件,对该建筑物的墙体裂缝及结构的损伤情况进行反分析研究.结果表明:分析所得建筑物内瓷砖裂缝范围大部分与实际检测结果吻合,计算得出瓷砖裂缝宽...

| Abstract: | One year after the completion of a certain station in Daxing metro line,cracks of different degree have been found on the walls and floors of the building near the station.Based on the test data and statistical data of the building,back analysis is carried out on wall cracks and structural damages of the building to determine whether the structure of the building is still safe by using the displacement method in structural mechanics and ABAQUS finite elements software.The results show that most of the tile ... |
