“…Xie et al 4 later presented an analytical solution for the one-dimensional nonlinear consolidation of double-layered soil associated with time-dependent loading on the basis of the work in Davis and Raymond. 3 More recently, Lee et al, 5 Zhu and Yin, 6 Chen et al, 7 Liu et al, 8 and Liang et al 9 further investigated the consolidation problems of multi-layered soil for different engineering conditions. Even though noteworthy progress has been made to study the consolidation problems of layered soil, the related research is still imperfect and needs further study for its complexity.…”

In this article, the exponentially time-growing drainage boundary is introduced to study the one-dimensional consolidation problem of double-layered soil. First, the one-dimensional consolidation equations of soil underlying a timedependent loading are established. Then, the analytical solution of excess pore water pressure and average consolidation degree is obtained by utilizing the method of separation of variables when the soil layer is separately undergone instantaneous load and single-stage load. The validity of the present solution is proven by the comparison with other existing analytical solution. Finally, the influence of soil properties and loading scheme on the consolidation behavior of soil is investigated in detail. The results indicate that, the present solution can be degraded to Xie's solution utilizing Terzaghi's drainage boundary by adjusting the interface parameter, that is to say, Xie's solution can be regarded as a special case of the present solution. The interface parameter has a significant influence on the excess pore water pressure of soil, and the larger interface parameter means the better drainage capacity of the soil layer.

“…However, to explain the entire nonlinear displacements mechanism of the model in the numerical simulation process, the linear regression model was used to illustrate the differential displacement of each model. Figures 4,5,6,7,8 and 9 show that the maximum differential displacement was reduced in single soil layers and multilayered soil when soil B was used in the model. This phenomenon shows the soil's mechanical properties are important in controlling differential displacement and maximum displacement of the soil model.…”

Differential displacement of soil foundation owing to the seismic excitation has received significant attention for evaluation infrastructure seismic resistance. The multilayered soil interaction requires investigation for the prediction and characterization of multilayered soil differential displacement. In this study, the Fast Fourier Transform (FFT) filtering method was applied for smoothing acceleration history. The numerical simulation performed using ABAQUS for soil layers interaction assessment. The statistical analysis was also applied for verification accuracy of numerical analysis and to predict the probability of the multilayered soil differential displacement occurrence. The mechanical properties of the soil, the number of soil layers, the location of soil arrangement, the type of seismic loading, and the accuracy of seismic loading were considered for modeling. The hexahedral mesh with a 500 mm size was selected in the numerical simulation. The results reveal the soil layer's interaction influence on differential displacement and flexibility of the multilayered soil. It was observed the nature of seismic loading has a significant influence on the type of soil in minimizing displacement. The soil layer arrangement controls the displacement magnitude and soil layer vibration magnitude. The conversion of the soil differential displacement to soil linear displacement and enhancement of the soil seismic stability occurred because of multilayered soil interaction and the nature of the seismic loading. This study's finding shows the statistical model verified and predicts differential displacement through a suitable application of the statistical model in geotechnical earthquake engineering. The presented method implies the appropriate design of multilayered soil. It can be alternative solutions to predict the differential displacement of multilayered soil by minimizing the number of the modeling through the applied statistical method. It characterized the conversion of the differential displacement to linear displacement by multilayered soil design occurrence.

“…The effective stress is often given as the difference between the total stress and the pore pressure, here b denotes the fraction of pore pressure that gives the effective stress, u denotes the pore pressure (EPP). The expressions of b have been presented by several literatures (Terzaghi 1936;Biot and Willis 1957;Skempton 1960;Schiffman 1970;Bishop 1973;Lade and Bore 1997;Chapuis 2004;Borja and Koliji 2009;Deng et al 2011;Liang et al 2017;Hong et al 2021), as shown in Table 1. Table 1 indicates that there is no available expression of b valid for all classes of soils.…”

Modelling the thermal–hydro-mechanical behaviour of unsaturated soils with a high degree of saturation using an extended precise integration method

Unsaturated soils with a high degree of saturation (HDS) are commonly encountered in marine and lacustrine sediments. In these soils, the gas phase generally exists in the state of discrete bubbles, which is sensitive to stress and temperature changes and can dramatically change the soil’s engineering properties. This paper explores the thermal-induced behaviour of HDS soils using an efficient extended precise integration method (XPIM). Biot poroelasticity theory, extended to include thermal effects and compressibility of gas-water mixture, is employed to analyze the soil behaviour under non-isothermal condition. Based on Laplace-Fourier transform and Taylor series expansion, such problems can be solved by XPIM. The robustness of XPIM was confirmed by comparing the present results with analytical solutions and test data. Extensive parametric studies are undertaken to examine both the effects of soil grain thermal expansion and anisotropic permeability on soil behaviour, and temperature effects on degree of saturation (Sr). The thermal-induced variations in Sr are more pronounced with lower initial values (e.g. 90% compared to 99%). These quantitative results demonstrate the benefits of the proposed method, which proves to be extremely efficient and several orders more precise than conventional numerical approaches, with its precision limited only by the computational effort used.
