Estimation of the level of recreational transformation of public green spaces by indicators of soil penetration resistance

open access: yesAgrology, 2020
The article shows the possibility of assessing the level of recreational transformation of public green spaces in terms of the soil penetration resistance and proved that the profile distribution of soil penetration resistance values is an information ...

Development of a portable multisensor platform for soil mapping [PDF]

open access: yesRevista Ciência Agronômica, 2023
Soil sensors are alternatively used to reduce the costs of soil sampling and be able to perform analyses in a laboratory. However, using individual sensors can result in low accuracy because the measured variable may be related to more than one soil ...

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

open access: yesYantu 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 ...

An investigation of correlation factors linking footing resistance on sand with cone penetration test results [PDF]

open access: yes, 2012
Significant research effort has led to improvements in our ability to estimate the ultimate bearing resistance of footings in sand. These techniques often estimate the footing resistance at relatively large displacements, typically 10% of the footing ...
