Determination of disturbance depth due to excavation using multifunctional CPTU tests
Yantu gongcheng xuebao, 2021 The disturbance depth of excavations is an important parameter for their design. Most of the existing methods for determining the disturbed depth are laboratory tests, which cannot reflect the in-situ stress state of soils.

A CPTU‐Based Prediction Method for Undrained Shear Strength With Quantified Uncertainty
Advances in Civil Engineering, Volume 2025, Issue 1, 2025.The engineering properties of seabed soils are crucial to the foundation design of offshore structures. Among them, the undrained shear strength (su) is a key parameter for evaluating the shear failure resistance of saturated cohesive soils. Although empirical equations based on piezocone penetration tests (CPTU) offer a convenient approach for ...

Resistivity Piezocone in the Conceptual Site Model Definition
Soils and Rocks, 2017 The management and remediation of contaminated sites are strongly dependent on the diagnosis process during the site characterization program. A Conceptual Site Model (CSM) elaborated by use of high-resolution site characterization (HRSC) tools allows for a detailed diagnosis of geo-environmental issues.

An Ensemble Method for Soil Parameter Prediction Based on Multisource Data Fusion
Advances in Civil Engineering, Volume 2024, Issue 1, 2024.Site investigation is crucial in geotechnical engineering. The cone penetration test (CPT) and the multichannel analysis of surface waves (MASWs) are widely used as geotechnical and geophysical methods, respectively. CPT offers high precision but requires a high cost and only provides soil information at limited locations.

, 1991 The piezocone test is an unsurpassed method of determining the strategraphy of all types of soils into which it can be pushed down. The method is well established for investigations in sand. In more fine-grained soils, increased use of the piezocone test would bring about a higher quality of the soil investigations in terms of determinations of ...
