Evaluation of the Preconsolidation Stress and Deformation Characteristics of Finnish Clays based on Piezocone Testing [PDF]

, 2020
The design of structures and infrastructures in soft soil areas represents an important challenge in geotechnical engineering owing to the poor soil properties in terms of strength and compressibility.

A Comprehensive Review of the Evaluation and Application of Engineering Properties of Expansive Soil Based on Piezocone Penetration Test (CPTU)

IOP Conference Series: Earth and Environmental Science
Abstract Expansive soil presents several challenges in civil and geotechnical engineering because of its distinctive physical and mechanical properties, including considerable volumetric fluctuations, non-linear stress–strain behaviour, and high permeability.

Prediction of stress history and strength of cohesive soils based on CPTU and data fusion techniques

Yantu gongcheng xuebao, 2019
The overconsolidation ratio (OCR) and the undrained shear strength (Su) are the basic mechanical parameters of soils, which can influence the deformation analysis and strength calculation of soils.

Case study and practical analysis of lateral bearing characteristics of a single pile in Taihu soft soils using CPTU data

Yantu gongcheng xuebao, 2018
The muddy silty clay is rich in organic matter and widely distributed in Taihu soft soil foundation. It has a large water content and compressibility and is in a state of flow plasticity. All of these make it have bad engineering properties.

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.

Determination of the Engineering Properties of Submarine Soil Layers in the Bohai Sea Using the Piezocone Penetration Test

Advances in Civil Engineering, 2018
Due to the complexity of marine geotechnical engineering, the harsh operating environments, loose subsea soils, and high water contents, it is extremely difficult to obtain soil samples while maintaining the in situ conditions in offshore areas.

Effect of piezocone penetration rate on the classification of Norweian silt [PDF]

, 2018
Interpretation of Cone Penetration Tests (CPTU) in intermediate soils is complex due to partially drained conditions during penetration. In order to gain more insight into the material behavior of silt during a CPTU, an intensive test program was carried
