Finite element method of the influence evaluation of the percentage of fine particles of marine clay at the different depth variations to the total volumetric strain of the soft clay ground is determined by the Viet Nam standard TCVN 4196:2012; TCVN 4102:2012; TCVN 4197:2012; TCVN 4199:2012. Results show clearly the percentage of the fine clay particle and the total volumetric strain (ε) with depths. The minimum value of 12% and 0.00002617 at 19.3m depth; whereas the maximum value of 38% and 0.00002609 at 25.3m depth. Moreover, a consideration of the relationship between Internal friction angle, Cohesive force, Water content, Saturation, Porosity, Viscosity, and Plasticity index with depths. Results show remarkably the increasing of the depths as the variations of the percentage of fine particles of marine clay and cohesive force, viscosity, water content, and porosity; compared with the decrease of the plasticity and internal friction angle. It is easy to conclude that the total volumetric strain of the soft clay ground is a stable and safe state to use and design the building, construction, and reference of engineers, geologists, scientists, and so on in the future.
