| 摘 要： | 在预应力混凝土结构中,由于锚固区受到较大集中力作用,很容易在受压区附近产生微裂缝甚至可能发生脆性破坏,对结构的使用寿命和安全将产生严重影响.如果清楚的分析出锚固区受力的详细特点,同时采取有效对策,这样就可以避免裂缝的产生或发生脆性破坏事故,从而提高结构的耐久性.

| Abstract: | In prestressed concrete structure,microcrack forms and even brittle failure occur very easily in compression zone due to the large concentrated force in anchorage zone,which has a serious effect on service life and safety of structure.If mechanical detailed characteristics in anchorage zone are analyzed clearly and effective countermeasures are adopted,the formation of crack and occurrence of brittle failure can be avoided,and then durability of structure can be increased. |
