GGU-SETTLE: System data (Ex. 1)

For example, you know the constrained modulus profile of 5 boreholes (BP 1 to BP 5) from field investigations. The boreholes have the following coordinates:

Borehole	x [m]	y [m]
BP 1	0.0	21.0
BP 2	1.0	6.0
BP 3	12.5	15.0
BP 4	25.0	22.0
BP 5	24.0	4.0

Table 1 Borehole coordinates

We have a 3-layer system. The individual layers have the following soil properties:

Layer no.	Soil type	Constrained mod. initial loading [MN/m²]	Constrained mod. reloading [MN/m²]	Unit weight of soil [kN/m³]
1	Silt	12	30	18
2	Sand	45	110	10
3	Clay, silty	6	15	11

Table 2 Soil types and soil properties

Unit weight input is only decisive if the limiting depth is to be calculated with a percentage value of the overburden stress. Constrained modulus input for reloading is only decisive when foundations with excavation unloading are being processed.

The layers at the individual boreholes, measured from ground level (GL), reach the following depths:

Borehole	Layer base 1 [m b. GL]	Layer base 2 [m b. GL]	Layer base 3 [m b. GL]
BP 1	2.00	3.50	15.00
BP 2	2.00	4.00	15.00
BP 3	2.00	5.00	15.00
BP 4	2.00	5.00	15.00
BP 5	2.00	4.00	15.00

Table 3 Layer depths

In the example, two foundations with the designations 'F1' and 'F2' are present.

Foundation	x (left [m]	y (bottom) [m]	Foundation pressure [kN/m²]	Length [m]	Width [m]
F1	4.0	14.0	200.0	7.0	4.0
F2	14.0	8.0	200.0	3.0	3.0

Table 4 Foundation dimensions and pressure

Both foundations have their base at 0.8 m below ground level.
