“…The 8-node brick elements were employed to simulate the sheet pile walls. In addition, 8-node brick, trilinear displacement, and trilinear pore pressure elements were used to model the soil domain [24,25]. The soil water characteristic curves (SWCCs) of the silty clay and sandstone are presented in Figure 3a, whereas the corresponding relative hydraulic conductivities, given as k w /k s , where k w and k s are the unsaturated and saturated coefficients of permeability, respectively, are presented in Figure 3b.…”

Cutting slope failures occur frequently along the high-speed railways in Northeast China during the construction due to snowmelt infiltration. This study addresses this issue by applying a three-dimensional numerical model. The influence of the depth of accumulated snow (ds), daily temperature variation (ΔT), and freeze-thaw (F-T) cycles on the seepage field and stability of cutting slopes is discussed. The results demonstrate that water seepage due to snowmelt infiltration primarily extends through the ground surface by about 10 m. The deep-seated instability is likely to occur under a prolonged and highly accumulated infiltration, while shallow failure is associated with intense, short-duration snowmelt infiltration. The maximum degree of saturation (Sr) and pore-water pressure (PWP) values are observed at the slope toe. Increasing ds and ΔT increase the Sr and PWP due to snowmelt infiltration and thereby decreases cutting slope stability. Compared to the ds and ΔT, the F-T cycle is more likely to cause slope failure. In addition, the F-T cycle also induces the reduction of soil strength and the crack propagation. Overall, the conducted study provided useful help toward the process of safer design for cutting slope along the high-speed railway in seasonally cold regions.

“…Calculations were made for the cases, when the groundwater level is on the surface, 0.50 m below and 1.00 m below the surface. Furthermore, it was analyzed in the case of potential backflow, when the water level of the lake is lower than the groundwater level [8]. In the numerical calculations, using Plaxis 3D, 15-noded wedge finite elements are used.…”

In the forthcoming years intensive renovation and reconstruction works can be expected on the banks’ freshwaters of Hungary. For the rehabilitation of the shores of Lake Velence works are starting in 2020. To support these investments there has been a demand for prefabricated reinforced concrete sheet pile walls. Realizing the opportunity, a major player in the market of pre-fabricated reinforced concrete elements for water way construction, CSOMIÉP Ltd. decided to develop a reinforced concrete sheet pile wall. In this study the development and complex structural and geotechnical design concept are shown through the major structural behaviors and useable geometries.
