[摘要] 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。

Abstract: The use of post-tensioned transfer plate in high-rise buildings in Hong Kong has been growing rapidly in the past two decades. It is now widely accepted by developers and structural engineers. Most transfer plates are poured in two or more layers, with a horizontal joint between, to suit site conditions and construction requirements. The goal of the article is to highlight the key issues of the design works based on many actual projects.
