钢纤维混凝土快速修补机场道面的应用研究

Application of Steel Fiber Reinforced Concrete on Urgent Repair of Airport Pavement

近年来,钢纤维混凝土凭借其较好的抗拉、抗折和阻裂增韧等性能,被越来越广泛地应用于机场道面、桥面和公路路面等工程中。目前,人们对钢纤维混凝土的基础理论(本构关系、阻裂机理等)和在道面或路面工程中的应用研究得较多,且已取得较大进展,但对钢纤维混凝土道面的薄层研究、钢纤维混凝土的综合经济评价研究甚少,需要进一步的完善。

In recent years,the application of steel fiber reinforced concrete on airport pavement,bridge deck and highway pavement becomes wider and wider because of its good properties such as tensile resistance,anti-fracture,crack arresting and toughening.Now,there is more research on basic theory of steel fiber reinforced concrete,such as constitutive relation and mechanism against crack,and great progress has been made.However,there is less research on thin layer of road surface and comprehensive economic evaluation of steel fiber reinforced concrete,which needs further improvement.
