摘要
结合合肥—六安一级水泥混凝土公路的检测,介绍FWD在检测水泥混凝土面板的传荷能力、板底脱空等方面的应用。分别用AASHTO截距法和单点弯沉值法对面板脱空进行判别,评价两种方法的关联性,并对压浆后28d和180d的面板检测结果进行综合分析,评价压浆处理面板脱空的效果。
Through inspection of Hefei-Lu＇an arterial cement concrete highway, the article introduces the application of FWD in inspecting load transfer ability and void under cement concrete pavement, etc. It discrimi- nates pavement void respectively by AASHTO intercept method and single point deflection method, evaluates the relationship between the two methods, and synthetically analyzes 28d and 180d results of pavement inspection af- ter grout jacking, then evaluates the effect of grout on treating pavement void.
