高效预应力砼,作为建设部“九五”重点推广的高新技术之一,在工程实践中表现出巨大的优越性。本文结合一具体工程对比分析,表明后张预应力砼平板体系用于多层住宅楼面结构综合成本与普通砼梁板结构相当,而使用功能却大大改善。
Highly efficient prestressed concrete, as one of the key technologies promoted by the Ministry of Construction in the “Ninth Five-Year Plan”, has shown great superiority in engineering practice. In this paper, a comparative analysis of a specific project shows that the comprehensive cost of the post-tensioned pre-stressed concrete slab system for the multi-storey residential floor structure is equivalent to that of an ordinary trussed beam structure, but the use function is greatly improved.
