Influences of friction fatigue effects of conductor-soil interface on penetration resistance of conductor of wellhead in deep water

Yantu gongcheng xuebao, 2020
The penetration resistance of deep-water conductor in clay is closely related to the friction fatigue at the conductor-soil interface. The shear stress at the conductor-soil interface decreases because of the friction fatigue caused by the installation ...

Analytical and experimental determination of the specific penetration resistance. Description of the facial and rear weakening free-surface effect

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2019
In the present paper, the main force parameter is estimated under the static tests. This parameter is the specific penetration resistance and it is generally believed that the parameter is a constant in case of static penetration.

Variability of Hydraulic Properties and Hydrophobicity in a Coarse-Textured Inceptisol Cultivated with Maize in Central Chile

Soil Systems, 2022
The O’Higgins Region, located in Central Chile, concentrates 40% of the country’s maize production, mainly under conventional tillage. This has generated soil physical degradation, modifying water movement on it, which varies even in short distances.
