摘　　要：以《混凝土结构设计规范》(GB 50010—2010)和《混凝土结构设计规范》(GB 50010—2002)的公式为基础,给出SP预应力空心板在二类环境和一类环境下按新旧混凝土规范设计的设计方法的对比。通过取SP18和SP38在普通民用建筑和工业建筑的设计算例,分析得出不同配筋不同环境条件下的SP板按新旧混凝土规范设计的差异,为工程实践提供设计参考。Based on the formulae in Code for Design of Concrete Structures（ GB 50010-2010 and GB 50010-2002）,the Spancrete hollow-core plank is given as an example to illustrate the changes on the pretensioned concrete member design in the environmental categories I and II. To provide a reference for the engineering practice,the different design according to the old and new design codes between the Spancrete hollow-core plank with different reinforcements in the different environmental categories are obtained by taking the design examples of SP18 and SP38 in common civil and industrial buildings.
