Understanding and assessing the spatial extent of liquefaction hazard requires the spatial dependence of geotechnical properties to be taken into account. In this work, novel multiscale random field models will be developed to characterize and quantify spatial variability of geotechnical parameters across scales. Such models will then be integrated with a simplified procedure for the probabilis...

the liquefaction resistance of soil can be evaluated using laboratory tests such as cyclic simple shear, cyclic triaxial, cyclic torsional shear as well as field methods like standard penetration test (spt), cone penetration test (cpt) and shear wave velocity (vs). in this regard, this study attempts to compare the results of the spt based on the simplified procedure proposed by seed and idriss...

The seabed Cone Penetration Test (CPT) system is a common method for investigating offshore soil. This paper focuses on new subsea CPT assessing physical and mechanical properties of marine sediments. enables automatic docking dismantling the probe rods underwater. constant-rate penetration mechanism basis core component CPT, allowing rod cone to penetrate seafloor sediment. Double hydraulic cy...

Due to the introduction of Eurocode 8, the structural design for seismic and dynamic effects has become more significant in Hungary. This has emphasized the need for more effort to describe the behavior of structures under these conditions. Soil conditions have a significant effect on the response of structures by modifying the stiffness and damping of the soil-structural system and by modifyin...

This paper undertakes liquefaction analysis with simplified procedures standard penetration test (SPT) data and cone (CPT) obtained from an offshore wind farm in the Changhua area. The soil resistance calculated by SPT-based procedure suggested Japan Railway Association was agreement laboratory results. CPT is widely used site investigation of farms. However, Taiwan’s registered professional en...

This study examines the capability of the Relevance Vector Machine (RVM) and Multivariate Adaptive Regression Spline (MARS) for prediction of ultimate capacity of driven piles and drilled shafts. RVM is a sparse method for training generalized linear models, while MARS technique is basically an adaptive piece-wise regression approach. In this paper, pile capacity prediction models are developed...

Random field modelling of soil variability allows significant statistical results to be inferred from field data; moreover, it provides a consistent framework for incorporating such variability in reliability-based design. Cone penetration testing (CPT) is increasingly appreciated because of its near-continuity and repeatability. Stressnormalised CPT parameters are included in widely used engin...

Road design is a complex, time-consuming, and very responsible process. To develop high-quality viable road project, it important to start with an accurate geological survey in order define the best layout. Moreover, geotechnical characterisation of foundation soils construction materials as well analysis assessment works are mandatory. Laboratory situ investigations complementary should be car...

The electric cone penetration test (CPT) has been in use for over 40 years and is growing in popularity in North America. This paper provides some recent updates on the interpretation of some key geotechnical parameters in an effort to develop a more unified approach. Extensive use is made of the normalized soil behaviour type (SBTn) chart based on normalized cone resistance (Qt) and normalized...
