【摘要】 利用动力响应模型试验装置,研究了高填路堤不同拓宽方式,以及工后重载动力响应高填路堤变形与破坏问题,新老路基不均匀沉降、新老路基的不稳定拓宽衔接是产生危害的主要原因,高填路堤不同拓宽方式下的重载动力响应试验研究成果为高速公路高填路堤拓宽改扩建工程提供了借鉴。更多还原

【Abstract】 Making use of the dynamic response model test device studied the high embankment road-basis of different widened ways,as well as the heavy dynamic response to the problem of high embankment roadbed deformation and damage,the new and old road-basis uneven settlement and the convergence of instability widen is the main reason for hazard,the study of Heavy-dynamic response under high embankment different widen ways which provides a reference for highway embanment widen engineering.更多还原
