＃在道路建筑中由于实施对土壤压实程度的控制,发生向试验室和检查站供给所需仪器的困难。为了能够对土壤湿度(含水量)和密实度组织广泛的检查,根据下列理论提出最简单的比重法。如所周知,建筑路堤所用的土壤在大多数情况下是处于三相状态的,即由土壤颗粒(固态),水(液态)和空气(气态)所组成。在上壤体积υο中,各相的含量等于: 按重量计 P_0=δυο+ωδυο克(1)式中: P_0——湿土重量; δ——干土容重,克/立方公分; ω——单位体积中含水量的重量百分比。按体积计
# Due to the control of soil compaction in road buildings, difficulties have arisen in supplying the required equipment to laboratories and checkpoints. In order to be able to organize a wide range of inspections of soil moisture (moisture content) and firmness, the simplest method of proportioning is proposed according to the following theory. As we all know, the soil used in the construction of embankments is in most cases three-phase, consisting of soil particles (solid), water (liquid) and air (gaseous). In the soil volume υο, the content of each phase is equal to: P_0 = δυο + ωδυο grams by weight (1) Where: P_0 - weight of wet soil; δ - dry soil bulk density, g / cm3; The weight percentage of water content per unit volume. By volume
