Insights from CPTu and Seismic Cone Penetration Testing in the Kathmandu Valley, Nepal

Frontiers in Built Environment, 2021
Seismic hazard assessment often relies on static piezocone penetration tests (CPTu) to estimate the cyclic resistance ratio (CRR) and for the evaluation of in situ soil behavior.

Mechanical properties of soils in internal waste bank of lignite mines and their primary characteristics [PDF]

Archives of Civil Engineering
The modern development of urban areas is related to, among others, the location of industrial facilities on the outskirts of cities. More and more often, commercial buildings are founded on areas that have not been used for construction so far.

CPTU-based probabilistic model and evaluation method for liquefaction of sandy and silty soils

Yantu gongcheng xuebao, 2023
The liquefaction of cohesionless soils is closely related to the pore water pressure. The in situ testing technology, piezocone penetration test (CPTU) which can directly measure the pore water pressure, has unique advantages in liquefaction evaluation ...

CPTU correlations for Norwegian clays: an update

AIMS Geosciences, 2019
Geotechnical design in clay areas in Norway is mainly based on piezocone (CPTU) tests results. Strength and stiffness parameters are usually derived from CPTU parameters and empirical correlations. In order to improve geotechnical design practice (e.g.

Mechanism of piezocone penetration tests under partial drainage conditions

Yantu gongcheng xuebao
In the natural state, the constraints of soils are between completely drained and undrained conditions. Due to the influences of the probe size, penetration velocity, soil properties and other factors, the partial drainage conditions will occur during ...

Measuring method for confined water level using piezocone penetration tests

Yantu gongcheng xuebao
The occurrence of confined water inrush and leakage is common in engineering projects such as foundation pits and tunnels. To economically, conveniently and accurately obtain the confined water level is of great significance for the guiding of ...

Changing climates and environments within the complex Middle to Late Pleistocene fill of an overdeepened valley at Niederweningen, Switzerland

Boreas, EarlyView.
Glacially overdeepened valleys in the northern Alpine Foreland preserve Middle to Late Pleistocene sedimentary sequences that may serve as valuable archives for reconstructing past environmental changes in response to shifts in climate. This study presents a multidisciplinary analysis of two sediment cores from the overdeepened Wehntal Valley at ...

Evaluating geoparameters of Maine sensitive clay by CPTU

, 2022
Using two sets of analytical solutions for CPTU in clays, a suite of theoretically-consistent geoparameters is shown to be in good agreement with independent laboratory and field test results obtained on sensitive Presumpscot clay in Portland, Maine, USA. Fall cone tests indicate a mean sensitivity of St ≈ 37.
