Simulation and Evaluation of the Pore water pressure (P) variations with the Depths, which did carefully by the Viet Nam Standard “TCVN 4197:2012”; “TCVN 8723:2012” and “TCVN: 8721: 2012. Research results presented particularly for Permeability Coefficient (χ) obtained 1.00E-08; whereas the minimum value has only shown 2.00E-09 at 0.5 kg/cm2 and 8.0 kg/cm2 at 24.3m depths. On the other hand, the pore coefficient (ε) variations decreased gradually as the increasing depths; whereas the minimum value obtained 0.685 at 27.3m depth. Moreover, standards viscosity (B) and Compaction density (ζ) increased gradually as the depths increased gradually. From the analysis, simulation of the Pore water pressure with depths was calculated particularly with remarkable results, which as done by the Plaxis 3D software, so results presented in 360 kN/m2 at 4.0m and minimum value of 20 kN/m2 at 38.0m depth. In conclusion, research results can be applied and credited affections to the construction deformation. Moreover, research results can be used as useful references for engineers of Civil, Geology, researchers, and scientists in the future.
