在众多高等级公路施工中,要求在短时期内用人工手段提高基础密实度等级和承载能力,这就给压实方式提出了新的要求。现有压实设备中使用效果相对较好的是振动式压路机,但它采用的是高频小振幅工作原理,对土壤的影响深度受铺层厚度的加大
In many high-grade highway construction, it is required to increase the basic density level and carrying capacity by artificial means in a short period of time, thus putting forward new requirements for compaction. Vibratory roller is relatively better used in the existing compaction equipment, but it uses the working principle of high frequency and small amplitude, and the influence on the soil depth is affected by the thickness of the ply
