摘　　要：以汉阳陵帝陵外藏坑展示厅工程为背景,结合国内大量研究资料及以往工程经验,给出了预应力混凝土T型截面梁的正截面承载力改进计算方法,通过对不同高跨比预应力混凝土梁的计算结果分析比较,表明该改进计算方法具有精度高,应用方便等优势,可运用于对计算精度要求较高的大荷载低高跨比预应力混凝土梁的工程设计,也可供类似工程借鉴参考.With the exhibition project of the Yangling Tombs of the H an Dynasty in the background, this paper brings forward the design and calculaton of prestressed concrete T beams with high load and low high-span ratio, combined with a great deal of domestic research datum and production. At the same time, the paper compares and analyzes the result of prestressed concrete beams with different high-span ratios and draws the correlative conclusion. It indicates that this improved calculated way has much predominance with high accuracy, conveniet uses. So it can be used to design engineering that requires high-calculated accuracy, and be referenced by for similar engineering.
