Therefore, to determine the settlements, it is necessary to know: the course of vertical stresses ?z with depth. The settlement-generating base stress ?1 = ?0 - ? ? h must be used, taking into consideration the stress reduction by the excavation unloading for the embedment depth of the foundations.

The influence factor for a saturated clay layer of semi-infinite extent for the immediate settlement of footing depends on its Size (dimensions of the loaded area) Shape (Rectangular, Circular) Rigidity (factor of rigidity ? flexible or rigid) and. Location of the loaded area.

Consolidation settlement occurs because water is gradually squeezed out from between the soil particles over time. This reduces the void space that separates the soil particles such that the soil moves downwards.

So, the Degree of consolidation depends on the thickness of the drainage path and coefficient of consolidation. where k = coefficient of permeability, mv = coefficient of volume change, ?w = unit wt. of water. Hence the degree of consolidation depends on the permeability of the layer also.

The primary consolidation settlement can be calculated from the coefficient of volume compressibility mv, which can further lead to the Young's modulus E? = (1 + v?)(1 ? 2v?)/[mv(1 ? v?)], with an assumed Poisson's ratio v?.

Consolidation settlement is time dependent natural process of fully saturated soil due to expulsion of water from the voids and compaction is instantaneous artificial process of partially saturated soil due to expulsion of air from voids.

Answer: Differential settlement may be modeled and calculated within SAFE by using multiple slab areas, and then by applying soil supports to each area of the foundation ing to recommendations from the soil report or the geotechnical engineer.

Therefore, to determine the settlements, it is necessary to know: the course of vertical stresses 03c3z with depth. The settlement-generating base stress 03c31 = 03c30 - 03b3 2022 h must be used, taking into consideration the stress reduction by the excavation unloading for the embedment depth of the foundations.
