进行3组双向网格状带齿加筋砂垫层加固道路软基的室内模型试验，对比研究不同的齿筋形式对双向网格状带齿加筋效果的影响.试验结果表明，双向网格状带齿加筋的抗拉强度能够得到较好利用，并能够较明显地提高路堤软基的承载力，减小路堤边坡的侧向位移和路堤软基的沉降及不均匀沉降，且加筋效果随着齿筋整体性的提高而增强.
Three model tests of reinforced sand cushion with denti-inclusions on soft ground under embankment were conducted, and the reinforcement effects of denti-inclusion forms compared. The results show that the biaxial grid reinforcement of denti-inclusions can better utilizing tensile strength. Reinforcement can be enhanced with improved integrity of denti-inclusions. The bearing capacity of soft ground is significantly increased, the settlement, differential settlement and the lateral displacement of embankment slope reduced.
