Numerical modeling and neural networks to identify model parameters from piezocone tests: I. FEM analysis of penetration in two-phase continuum

This study presents a numerical approach designed for material parameter identification for the coupled hydro-mechanical boundary value problem (BVP) of the piezocone test (CPTU) in normally and lightly overconsolidated clayey soils.

Determination of Consolidation Characteristics in Fine Soils Evaluated by Piezocone Tests.

, 1999
There has been an increasing trend to use the piezocone penetration test (PCPT) as an in situ tool of choice for determining the consolidation and flow characteristics of cohesive soils.

An artificial neural network based model to predict spatial soil type distribution using piezocone penetration test data (CPTu)

, 2019
Soil types mapping and the spatial variation of soil classes are essential concerns in both geotechnical and geoenvironmental engineering. Because conventional soil mapping systems are time-consuming and costly, alternative quick and cheap but accurate ...

The load-bearing capacity of screw piles in silty soils based on mechanical, piezocone and seismic soundings

To accurately determine how piles behave in a particular situation, a static pile loading test is considered the most reliable method, although its implementation is restricted to special cases due to its high cost.

The piezocone in lightly over consolidated clay

, 1989
A laboratory experimental programme was carried out to investigate the behaviour of the piezocone in lightly over consolidated clay. The clay samples were prepared from reconstituted kaolin.

A CPTU-based earth pressure model for deep excavations under complex environment and its practical application

Yantu gongcheng xuebao
The determination of earth pressure is a key element for the design of retaining structures of deep excavations. However, the existing earth pressure models can not reasonably consider the change of soil properties induced by excavation activities.

Physical property of MICP-treated calcareous sand under seawater conditions by CPTU

Biogeotechnics
MICP (Microbially induced calcite precipitation), an environmentally friendly soil improvement technique, has great potential in ocean engineering due to its ability to promote the precipitation of calcium carbonate through microbial activity to enhance ...
