摘要: 针对钢筋混凝土路面板悬空水毁灾害,提出了悬空钢筋混凝土路面板锚拉加固方法,由锚固钢绳、钢绳支墩和锚杆三部分组成;采用结构力学方法,建立了悬空钢筋混凝土路面板弯矩、最大允许宽度及锚固钢绳拉力的计算公式;工程实例分析表明:所建立的悬空钢筋混凝土路面板锚拉加固方法有较强实用性,可实现钢筋混凝土路面板悬空灾害的应急抢修。

Abstract: Aiming at the water ruin disaster of the suspended reinforced concrete road slab,the anchor reinforced method for the suspended reinforced concrete road slab was proposed, which was composed of three parts, i.e., anchor stress rope, buttress and anchor rope. The calculation formulas of bending moment, the maximum width permitted and the anchoring wire cable tension force of the suspended reinforced concrete slab were established. Engineering case studies show that the method of reinforced concrete pavement slab established has strong practicability, which can realize emergency repair of the suspended reinforced concrete slab disasters.

Key words: road engineering, highway water ruin, anchor reinforce, rapid repair, disaster
