通过桥涵构造物台背填筑压实现场试验,得出了多种振动压路机在不同填筑材料下振动压力的传递深度及振动影响范围,并对多种填筑材料随压路机吨位的增加其振动影响深度的变化作了深入的探讨,提出了对不同填筑材料进行压实时所需要的压路机的种类及相应的最佳松铺厚度,为台背填筑压实施工时的压路机选择提供了科学依据。
Through field test of backfill compaction of bridge and culvert structure, the transmission depth and vibration influence range of vibration pressure of various vibratory rollers under different filling materials are obtained, and the vibration of a variety of filling materials with the increase of roller tonnage The influence of depth on the changes made in-depth discussion put forward for the compaction of different filling materials required for the type of roller and the corresponding optimal thickness of the shop for backfill compaction construction of the roller to provide a scientific choice in accordance with.
