“…The total number of V S data points is 258. In order to compare these V S measurements with those of the CPTu data, the midpoint depth for each sampling interval is used and the other parameters are averaged, as recommended by Tonni & Simonini (2013) and Andrus et al (2007). This procedure attenuates the effects of using long intervals for shear wave velocity measurements and the subsequent comparison with CPTu data.…”

A detailed characterization of the shear wave velocity profile is an essential tool in the resolution of a variety of seismological and geotechnical engineering problems. The main objective of this study is to present equations capable of providing reliable shear wave velocity profile estimations based on CPTu parameters. The results of a series of pioneering in-situ seismic piezocone penetration tests on the Brazilian continental margin are presented in this paper. A complete geological and geotechnical characterization of multiple sites was performed. Multiparameter and single parameter correlations were proposed between the measured shear wave velocity and the piezocone penetration test parameters. The suitability of the proposed correlations was evaluated by means of a statistical analysis and compared to the performance of previously published correlations using the test data parameters as input. The results show that the study was successful in presenting equations with superior performance for local soil conditions. Furthermore, this study yielded new reliable correlations that will benefit future projects in similar offshore environments.

“…Bihs (2021) reports that both the drained and undrained strength depends on the choice of penetration rate. Senneset et al (1988), Lunne et al (1997), Robertson (2009) and Tonni & Simonini (2013) discuss constrained and small strain shear modulus.…”

“…Soil is assumed to be isotropic and linear elastic. Young's Modulus for the shallow anthropic layer is estimated on the basis of CPTU and laboratory test interpretation according to Biscontin et al (2007) and Tonni and Simonini (2013) and set to E=100 MPa, whereas Poisson's ratio is reasonably equal to ν=0.3.…”

Sea level rise and high tide events are threatening many coastal cities, which require adequate and sustainable protection measures. The historic city centre of Venice (Italy) is often flooded during very high tide events, especially the area of St. Mark's island, which is at the lowest elevation among all the islands forming the city. In order to design cost effective protection interventions to safeguard the historical heritage, a deep understanding of flooding mechanisms and the relationship between groundwater pressure and tidal oscillations are necessary. Geotechnical survey and analyses play an important role in this process. This paper presents the results of a recent monitoring campaign carried out in St. Mark's island. A simplified one-dimensional analytical model has been derived for saturated conditions to understand the key parameters that govern tidal induced pressure oscillations in soil (material properties, geometrical features and wave properties). Additional features, such as partially saturated soil conditions and twodimensional effects, have been investigated numerically. Results show that significant pressure oscillations occur in the subsoil, which should not be neglected for the stability of horizontal architectural structures, such as the historical mosaics and paving. However, seepage flow rate is small, thus its impact on the drainage system is limited in terms of water discharge.
