摘要
以保定—阜平高速公路填石路堤为研究对象,建立有限元模型模拟路基及夯击功能,并结合现场试验,分析强夯法在处理填石路堤时的有效加固范围,从而可确定夯击次数、单层填筑厚度、夯点布置等施工参数。
Taking the Baoding-Fuping expressway rock embankment as the object of study, the finite element model is established to simulate subgrade and dynamic consolidation function. The effective reinforcement scope in embankment constructed with dynamic consolidation method is analyzed, combined with the field test. It has determined the times of tamping, single-layer reclamation thickness, arrangement of tamping point and so on.
