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.

Study on the Influence of Pile Installation Disturbance on the Settlement of Composite Foundation

Applied Sciences
The disturbance generated during the pile installation process increased the compressibility of the soil between the piles, thereby causing additional settlement of the composite foundation.

Comparison of the Piezocone Penetrometer (CPTU) and Flat Dilatometer (DMT) Methods for Landslide Characterisation

Geosciences
The increasing occurrence of landslides worldwide causes many human casualties and huge socio-economic losses. Therefore, the fastest and most accurate characterisation of landslides is important.
