The parameters of subsoil for subsoil defined under a 1D member are:
|
C1x |
resistance of environment against ux (deformation in local x direction) |
|
C1y |
resistance of environment against uy (deformation in local y direction) |
|
C1z |
resistance of environment against uz (deformation in local z direction) |
|
C2x |
resistance of environment against dux/dx |
|
C2y |
resistance of environment against duy/dx |
|
C2z |
resistance of environment against duz/dx |
Note: In the complete set of 6 parameters C, four parameters are significant and, if available, can be determined from the C parameters of subsoil 2D model in EPW Soilin module and from the stiffness of boundary bonding "k" modelling the effect of settlement basin:
|
C*1x (MN/m2) |
= b (m) C1x (MN/m3) |
|
C*1y (MN/m2) |
= b (m) C1y (MN/m3) |
|
C*1z (MN/m2) |
= b (m) C1z (MN/m3) + 2 k (MN/m2) |
|
C*2z (MN) |
= b (m) C2x (MN/m) |
|
|
where b is the width of the member. |
It is not recommended to use the remaining two parameters. Reliable experimental data are not available for C2x and C2y.
