Coefficient m
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 F1 -F8 - with deformation modulus Edef < 4 MPa - nonoverconsoludated - soft to hard consistency (all 3 attributes must be fullfiled), filling, made - ground secondary and tertiary sediments rocks class R1, R2 | 0.1 |
fine soils class F1-F8, not belonging to coefficient m = 0.1 or 0.4 or 0.6 sands and gravels class S1, S2, G1, G2 under GWT rock class R3, R4 | 0.2 |
Sands and gravels class S1, S2, G1, G2 above GWT sands and gravels with clay, silt or fine soil admixture soils class S3, S4, S5, G3, G4, G5 rocks class R5, R6 | 0.3 |
