| 摘 要： | 结合105国道吉安段混凝土路面改建工程，对比分析了基于FWD各种检测方法的原理和特点，通过FWD逐板实测弯沉后进行判别，并与用灌浆量判别脱空板的个数相比较，结果表明截距法相对效果较好。选择三段脱空较严重路段作为试验段，采用板底压浆方式进行处治，效果良好。

| Abstract: | Combined with concrete pavement reconstruction engineering of Ji＇an Section in No.105 national highway,this paper analyzes the principle and characteristic of each detection method based on FWD after actual deflection of slab and compares the quantity of hollow slab by grouting amount.The result shows that intercept method has relatively better effect.Through test on three severely hollow sections,bottom grouting has better effect in cavity treatment. |
