Description of the problem
One of the difficulties to apply the Continuum model to practical problems is that the long computation time. Therefore, a comparison for time and accuracy required for analysis the raft by the Continuum model is carried out by the following calculation methods:
|
- Modification of modulus of subgrade reaction by iteration after Ahrens/ Winselmann (1984) (Winkle's model/ Continuum model) |
|
- Modulus of compressibility method for elastic raft on layered soil medium after El Gendy (1998) (Solving system of linear equations by iteration) (Layered soil medium - Continuum model) |
|
- Modulus of compressibility method for elastic raft on layered soil medium (Solving system of linear equations by elimination) (Layered soil medium - Continuum model) |
To evaluate the iterative procedures used in ELPLA, consider the raft shown in Figure 30. The raft has a dimension of 10 [m] × 20 [m] and 0.6 [m] thickness.
