The paper presents a selected aspect of the determining the initial soil shear modulus value on the research example in resonant column – torsional shear apparatus (RC / TS). There are presented the significance of the initial value of shear modulus in design of offshore wind power plant foundations and the importance of its variability in the function of cyclical shear strains of soil related to the impact of sea and atmosphere on the designed structures. Based on the conducted analyses, a new methodology for interpreting the TS test results of soil has been proposed. It allows estimating the values of the shear modulus in the full range of shear strains occurring in issues closely related to the design and construction work of offshore wind power plant foundations.

“…According to the results of Bahloul [8], it can be concluded that Plaxis software predicted the real consolidation settlement after comparing the settlement observed in the field with that obtained by using Plaxis program, therefore, the finite element simulation is performed by the Plaxis program; a numerical investigation was carried out by a soft soil model to represent the load settlement and time settlement behavior of footing. The soft soil model is a Cam-Clay model that is utilized especially to study the primary compression of normally consolidated clay, so based on finite element analysis by this model found in the Plaxis program, the trends of ground settlement can be depicted accurately [9].…”

In the present study, laboratory model tests and numerical analysis are carried out to study the immediate, and consolidation settlement of shallow foundations rested on clayey soil. The purpose is to evaluate the immediate and consolidation settlement of different cases and compares them with the calculated values using theoretical equations; the numerical analysis is utilized by the Plaxis-3D program for developing the finite element model, whereas the soft soil model was used for simulation. It was studied the effect of three parameters on the behavior of the foundation for immediate and consolidation settlement, these parameters are soil cohesion, the pressure applied on the foundation, and layer thickness. The obtained results indicated that the simulation using the soft soil model underestimates the immediate settlement by about 30 % and gives excellent results for predicting consolidation settlement. The total settlement of shallow raft foundation rested on a clay layer of depth three times raft width to one time was increased by about 66 %. The consolidation settlement is much higher than the immediate in clayey soils, however, the average of immediate to consolidation settlement is equal to 0.3 % for pressure 20 kPa, and increases with rising applied pressure until it reaches 1.2 %. The numerical analysis revealed a lower value than the calculated using the theoretical equation for immediate settlement, while for consolidation settlement, the results are close except for the soft clay condition cu = 20 kPa.

“…También, (Zuo et al, 2018) mencionan la descripción de la conversión del drenaje por consolidación a la base compuesta basada en la función de distribución Ascend Semi-cauchy de la teoría de las Matemáticas Fuzzy, presenta la expresión de tiempo del grado de consolidación, pues verifica la precisión computacional de la expresión mediante datos medidos y confirma asentamiento total de la precarga secundaria después de la comparación y el cálculo por este método curva e-lop, que considera la influencia histórica del esfuerzo del suelo es más preciso al calcular el total asentamiento de la precarga secundaria, este método puede lograr la precisión de cálculo del asentamiento la postconstrucción con la expresión de grado de consolidación mencionado anteriormente. (Jie et al, 2017) comentan en un proyecto de construcción de una isla artificial basado en la recuperación de tierra marina a gran escala, el asentamiento del suelo es clave para afectar la operación. El asentamiento del suelo se obtiene observando las cartas del microscopio electrónico de escaneo-SEM, escanea la superficie de las muestras tratadas con un enfoque de haz de electrones y genera varias señales a diferentes profundidades, algunas fotos SEM reflejan lo esencial de la microestructura que influyen en la deformación y esfuerzo del suelo., mediante la combinación de cálculo numércio de la teoría de consolidación unidimensional de Terzhaghi y bidimensional de Biot.…”

El objetivo de esta presente investigación, es una revisión literaria de 60 referencias bibliográficas de las cuales 46 son artículo de revistas indexadas en la base de datos Scopus y Scielo, 13 libros y 01 tesis que sustentan la evolución de la teoría de la consolidación unidimensional propuesta por Terzaghi en 1925 para predecir los asentamientos producto de la disminución de los vacíos debido a la expulsión parcial y total del agua, A través del tiempo está teoría tomó mayor soporte teórico y es usada en muchos proyectos geotécnicos y civiles para el cálculo de asentamientos a través de programas de elementos finitos como PLAXIS y FLAC 3D. Se concluye que se ha logrado grandes avances de modelar el comportamiento hidromecánico de suelo en programas de elementos finitos para poder explicar la heterogeneidad del suelo y explicar la interacción que debe de tener con la superestructura.
