摘　　要：随着民用建筑越来越多的大跨度梁出现,预应力技术也被广泛应用于其中。论文对民用建筑中常见的几种大跨度预应力梁结构方案进行了受力分析和综合经济指标对比,为大跨度梁的结构设计提供借鉴。The prestressed technology is widely used in the construction of more and more large span beam. In this paper, the stress analysis and comprehensive economic indicators of several prestressed concrete beam structure in civil building are analyzed and compared. It provides a reference for the structural design of large span beam in the future.
