随着城市建筑的发展,用地越来越紧张,地下室空间的利用越来越重要,本文结合工程实例,对目前大面积地下室车库上浮问题进行了分析,从而提出了抗浮加固设计的基本思路,介绍了新增预应力锚索在地下室抗浮加固设计中的计算方法,以供同类工程参考。
With the development of urban construction, more and more intense land use, the use of basement space is more and more important. In this paper, combined with engineering examples, the current large area basement garage floats were analyzed, and the basic idea of anti-floating reinforcement design was put forward. The calculation method of new prestressed anchorage cable in anti-floating reinforcement design of basement is introduced for reference of similar projects.
