最近的二十年里,香港的高层建筑中采用后张有粘结预应力技术的转换层厚板有了迅速的增长。由于各种实际条件的限制,要求转换层厚板的设计必须满足分层浇捣、分段张拉的施工工艺。本文立足于大量的实际工程经验,力图勾画出这种特殊的组合型结构在香港现今的设计概貌。 In the recent two decades, there has been a rapid increase in conversion floor slabs in the high-rise buildings of Hong Kong using post-tensioned bonded prestressing technology. Due to a variety of practical conditions, the requirements of conversion layer thick plate design must meet the layered pouring pounding, sub-tensioning of the construction process. This article based on a large number of practical engineering experience, trying to outline the design of this special combination of structure in Hong Kong today.
