摘要
从预应力混凝土结构的耐久性机理出发,列出影响预应力混凝土耐久性的主要因素,并针对其作用机理提出相应建议。在对目前国内外几种主要的预应力混凝土结构形式的耐久性进行详细比较后,得出在选择结构形式时应对预应力与结构耐久性作慎重考虑等结论。
To begin with the mechanism of durability of concrete structures, the major factors that affect the durability are enumerated and suggestions given out according to the mechanism. After comparing in detail the durability of the main forms of pre-stressed concrete structure, it is concluded that the structural durability should be considered discretely when selecting structural forms.
