| Abstract: | Effect of soil formation on packing and on vertical stresses in soils The relationship between void ratio and vertical stress was investigated for 34 profiles (loess, glacial till, sands) mostly under forest and some under meadows. Development in terrestric forest soils obviously results in ?non overconsolidated”? structure. The stress distributions as a function of depth partly point to constant shear parameters, partly to differences in the profile, especially clear in the case of Podsol and Sandbraunerde. Whereas the absolute value of the void ratio can be explained by the soil-own shear parameters, the decrease of void ratio as a result of equal load increments will be explained by the extent of translation, which is necessary to increase the mean number of grain contacts. |
