1. The borehole record

In order to identify the stratification and the geotechnical characteristics of each soil layer a 8m

deep borehole was perform. resulted the soil stratification and the characteristics presented below.

The following activities are required to be completed:

- soil identification;

- 

calculation of the subsequent geotechnical indices: γd, n, e, Sr, Ip, Ic, M2 - 3;

- characterization of the soils based on: Sr, Ip, Ic, M2 - 3;

-  borehole record form.
