List FIVE factors that possibly affecting the rock testing results in the laboratory?

Part of an on-site investigation for a geotechnical study where a reservoir will be builtrectangular for storage yielded the following results: Depth (m)                        Soil Classification                                γt  (kN/m3)             0-4                                                    ML                                             18.6 4-5                                                SP-SC                                           19.65-9                                                    CH                                             17.79-30                                                 CH                                             18.2+30                                         weathered rock                                      - a)  Calculate and plot the total stress, effective stress, and pore pressure. Assume that the level water table is 1.8 m from the surface. Consider the specific weights of the soil of 1.8 m down as saturated. From 0 – 1.8 m, there…
