ABSTRACT
The case of study is related with the connection between section A2-2 and section B1.2 along the alignment of Istanbul Kadikoy-Kartal Metro, located approximately between the kilometres 5 + 050.00 and 5 + 100.00, as shown in Figure 3. 2.2 Geological setting
Based on the Geological Geotechnical report elaborated by the Avrasya Metro Grubu, the study area was mainly excavated in the Kartal Formation. To properly represent the geological context, a set of lower and upper bound parameters for rock were considered in order to face the possible range of geomechanical
conditions. Furthermore, the parameters of “residual clay” were considered as for the more superficial strata of the ground. The parameters of the material used in the numerical models were obtained through statistical processing of all the available data and are summarized in Table 1.
