Coefficient m
The correction coefficient of surcharge due to structural strength m determines the structural strength of soil.
Values of the correction coefficient of surcharge m
Type of fundamental soil | m |
Very compressible fine soils class MG-CE - with deformation modulus Edef < 4 MPa - non overconsoludated - soft to hard consistency (all 3 attributes must be fulfiled), filling, made - ground secondary and tertiary sediments rocks class R1, R2 | 0.1 |
fine soils class MG-CE, not belonging to coefficient m = 0.1 or 0.4 or 0.6 sands and gravels class SW, SP, GW, GP under GWT rock class R3, R4 | 0.2 |
Sands and gravels class SW, SP, GW, GP above GWT sands and gravels with clay, silt or fine soil admixture soils class S-F, SM, SC, G-F, GM, GC rocks class R5, R6 | 0.3 |
eluvium of igneous and metamorphic rocks | 0.4 |
