[提要]  将目前国内先进的预应力理论与技术应用于一幢28层高层建筑中，建立并研究了预应力扁梁框-剪结构体系；提出有粘结与无粘结相结合的预应力双筋梁抗爆新结构；将大跨无粘结预应力连续地基梁用作抗浮结构。为今后进一步发展及推广预应力新技术提供了参考。

The advanced theory and technique of the prestressed concrete structure are applied to a highrise building of twenty-eight storeys. The main achievements are as follows:establishing and studying the prestressed concrete widened beam frame-shear wall structure system; using the bonded and unbonded doubly pre stressed beam to resist the explosion; employing the large span unboned prestressed continuous beam as a resisting water-buoyancy structure. Valuble data and reference for prestressing technique are presented.
Keywords: prestressing; widened beam; frame-shear wall structure; resisting explosion; unbonded prestress continuous beam
