We usually use several experience-equations when estimate strength increase caused by overburden pressure.
These equations are suggested by Skempton & Henkel(1953), Bjrrum & Simons(1960), Karlsson & Viberg(1967).
The suggested equations are calculated by % or decimal of plasticity index(PI), liquid limit(LL) and liquid index(LI)
But Equations have no guarantee in actual ground, the equations are just experience-equations.
We estimate strength in ground under overburden pressure, design and check stability by experience-equation through actual cases of construction.
So this paper checks a accuracy of experience-equation in our country and suggests compatible experience-equation.
These equations of Skempton & Henkel(1953), Bjrrum & Simons(1960), Karlsson & Viberg(1967)have a over estimation for 30~50%, when overview in our ground.
So We are very carefully to use a experience-equation.
This paper suggests a estimated equation of strength increase by overburden pressure through actual embankment construction.
This estimated equation has 15% error but has more accuracy than equation of Skempton & Henkel(1953), Bjrrum & Simons(1960), Karlsson & Viberg(1967).
This estimated equation should be modified and corrected by many cases of actual construction.
