Unformatted text preview: of weakness (esp. layer interfaces) may be analyzed using a series of straight lines (wedges) o the actual failure surface will be a combination of the above and three dimensional o analyses are necessarily iterative to find the weakest failure surface o determination of soil properties has a bigger impact on safety than defining the actual failure surface o both short and long term stability should be considered short term depends on undrained soil parameters and total stresses long term depends on drained soil parameters and effective stresses...
