摘要
本文论述了厦门高崎国际机场水泥混凝土道面存在的病害,运用近年来发展起来的混凝土损伤力学与混凝土断裂力学理论,对混凝土道板贯通裂缝机制、温度应力,裂缝尖端附近应力场强度作了分析,并采用早强膨胀钢纤维混凝土对贯通裂缝做了修补加固,使机场混凝土道板符合安全飞行要求。
The article describes the diseases existed on the concrete pavement of Amoy Gaochi International Air-port. The recently developed theories of concrete damage mechanics and concrete fracture mechanics are used for analyzing the joined-up cracks on the concrete pavement, the concrete temperature stress and the stress field near the crack peak. And the high-early strength inflation glass fibre is adopted to repair and strengthen the joined-up cracks, thus making the concrete pavement of the airport fit to the require-ment of safe flight.
