On Research of the Stability Technology of Coarse-Grained Salty Soil Subgrade

Study on behavior of coarse grained soil and its modeling;

Influencing factors for particle breakage of coarse grained soil

The paper design the inorganic binding materials stabilizing chlorine saline soil of fine-grain to use in the road base or subbase through analyzing the soil characteristics of Yellow River wash plain coastal region, considering the feature of the climate and hydrographic of this area, and investigating the supply of the material.

From the principle, the paper obtained the formula of maximum dry density of oversize coarse-grained soil, ρ_(dmax)=ρ_(dmin)+1Aρ\-\{do\}-B(ρ_(do)-ρ_(dmin)), which is better than the formula ρ_(dmax)=f(ρ_(dmin),Δρ_d)≈ρ_(dmin)+(ρ~′_(dmax)-ρ~′_(dmin)) in .
