摘　　要：在模型试验的基础上,建立了静力触探的锥尖阻力与公路桥涵台背回填中粗砾砂的相对密实度的经验公式。通过现场试验,结合分析前人的研究成果,论证了用静力触探的锥尖阻力Qc来评价台背回填砂的相对密实度是可行的。<Abstrcat>Based on the results of model tests, two experiential equations are set up about the cone resistance of the static cone penetration and the relative density of coarse sand filled in the back of bridge and culvert. Field test and analysis based on former study results of others have proved the feasibility of evaluating the relative density of coarse sand filled in the back of bridge and culvert by applying the cone resistance of the static cone penetration.
