在国内外预应力碳纤维板加固混凝土受弯构件研究成果的基础上,对国产预应力碳纤维板的长期徐变性能进行室内试验,并对预应力张拉锚具锚固端碳纤维板的滑移进行观测。试验结果表明:国产碳纤维板在50%左右极限应力长期张拉作用下,碳纤维板徐变量及预应力张拉机具锚固端碳纤维板滑移量都很小,为国产预应力碳纤维板加固混凝土结构的长期性能研究提供了可靠的理论数据。 Based on the research results of flexural members reinforced by prestressed carbon fiber reinforced plastic (CFRP) both at home and abroad, the long-term creep properties of domestic prestressed carbon fiber sheets were tested in-house and the slippage of anchored CFRP sheets of prestressed tension anchors was observed . The test results show that the creep of carbon fiber board and the slip of carbon fiber plate anchorage end of prestressed tensioning machine are very small under the condition of long-term tension of 50% Long-term performance studies provide reliable theoretical data.
