摘要
随着地下空间的广泛利用,地下室的层数也随之增加,地下水丰富的沿海城市中多层地下室的抗浮问题已不容忽视。正确的计算方法、合理的抗浮措施,是避免地下室上浮、开裂的前提保障。本文通过工程实例,分析了预应力锚索在多层地下室抗浮技术中的应用,阐述了预应力锚索在设计、施工阶段的关键性技术问题。
Along with the extensive utilization of underground space, the layers of basement also increased, which makes the multi -layer hasement＇s anti - floating problem cannot be ignored in coastal cities. The adequate method of calculation and reasonable anti - floating measures can effectively relieve the base- ment buoyancy and cracking. This article analyses the application of pre - stressed anchor cable in multi - layer basement anti - floating tcchmology and ex- pounds the key technical problems of pre - stressed anchor cable in the design and eonstruction phase.
