Cone penetration tests (CPTs) can quantitatively inform about the mechanical state of a sand. However, relating measured cone resistance values to sand requires complex back-analysis processes occurring in soil during test. This paper provides new evidence value added this area by modern large-deformation modelling based on material point method (MPM). It is shown that accurate simulation relat...

Cone penetration testing (CPT) is a cost effective and popular tool for geotechnical site characterization. CPT consists of pushing at constant rate an electronic penetrometer into penetrable soils recording cone bearing (qc), sleeve friction (fc) dynamic pore pressure (u) with depth. The measured qc, fs u values are utilized to estimate soil type associated properties. A method from measuremen...

The evaluation of liquefaction potential of soil due to an earthquake is an important step in geosciences. This article examines the capability of Minimax Probability Machine (MPM) for the prediction of seismic liquefaction potential of soil based on the Cone Penetration Test (CPT) data. The dataset has been taken from Chi-Chi earthquake. MPM is developed based on the use of hyperplanes. It has...

In this study, three-dimensional simulations of cone penetration tests (CPT) in cemented sandstone have been investigated using the Discrete Element Method (DEM). We generated realistic grain size distribution numerical Ustyurt-Buzachi Sedimentary Basin samples. Numbers CPT at different bond strength values were performed with penetrometer vertically moved down a constant rate. The results real...

A multi-year cone penetration testing program was conducted at a landslide subject to episodic retrogression in Mud Creek, Ottawa, assess whether hand-operated mobile test (CPT) could yield new insights into the current degree of remolding under progressive failure metastable areas where conventional tracked rigs are unable gain access. The CPT rig permitted tests be performed through entire th...

The potential for liquefaction triggering of a soil under a given seismic loading is measured herein by probability of liquefaction. The first order reliability method FORM is used to calculate reliability index, from which the probability of liquefaction is obtained. This approach requires the knowledge of parameter and model uncertainties; the latter is the focus of this paper. An empirical m...

The cone penetration test-based simplified liquefaction triggering evaluations are largely based on linking manifestations in the field to resistance. These relationships interpreted such a way that for given resistance, resistance increases as non-plastic fines content (FC) increases. However, several studies have indicated discrepancies this relationship. Hence, there is lag rational scientif...

In ad 1362, a major storm surge drowned wide areas of cultivated medieval marshland along the north-western coast Germany and turned them into tidal flats. This study presents new methodological approach for reconstruction changing coastal landscapes developed from site in Wadden Sea North Frisia. Initially, we deciphered long-term as well event-related short-term geomorphological changes, usin...
