“…[6,38], the fictitious domain approach can lead to mesh distortions of void (or low-density) elements under finite deformations which leads to numerical convergence issues during the solution process. Several strategies have been proposed to tackle this issue, e.g., neglect of the degrees of freedom (DOFs) related to void elements in the NR convergence [6], element removal and reintroduction strategy [47], novel topological parameterization by inter-element zero-length elastic links [48], element distortion indicator informed design update [49], linear energy interpolation scheme [16,38,50], etc. Among them, the adaptive linear energy interpolation method proposed by the authors [16] is adopted in this work.…”

In order to improve the understanding of such floodplain sediments and determining the validity of the tests, an extensive series of multifunctional seismic piezocone tests with pore pressure dissipation phase have been performed and supplemented with conventional borings, standard penetration, laboratory testing, and so forth. Sounding results from SCPTU were used to determine the stratigraphic profiles and the soil characteristics of two anchorage sites. A comparison of the boring and laboratory results with the CPTU profiles showed that the CPTU provided excellent information on soil stratigraphy and good guidance for determination of behavior and engineering implications of recent Yangtze River floodplain. At an area where local correlations based on modern SCPTU do not exist, methods for estimating coefficient of earth pressure at rest (K0), hydraulic permeability (kh), and equivalent stiffness (G0) associated with bridge foundation design are presented, compared, and verified. Results also illustrate the complexity and variability of the floodplain stratigraphy and soil properties, which means that the suggestions in this study should be updated when more local experience is obtained. This case study suggests that such enhanced seismic piezocone test should be considered as a potential tool and the instrument of first choice in site characterization programs for design of bridges founded on complicated soils in China.
