Full-flow cyclic degradation and micro-structure of representative deep-sea soft clay

open access: yesYantu gongcheng xuebao, 2019
The geotechnical properties of deep-sea soft clay are quite different from those of terrestrial or offshore clay. For the representative deep-sea soft clay collected from the western region of South China Sea, an improved full-flow penetration device is ...

Modified p-y Curves Method Based on Degradation Stiffness Model of Sand

open access: yesShanghai Jiaotong Daxue xuebao, 2020
Most of the existing p-y curves are based on the model test results of small-diameter pile under cyclic loading of finite times, which makes it difficult to accurately describe the displacement accumulation of large-diameter pile under long-term ...

Cyclic Degradation Characteristics of Undisturbed Soft Clay considering Anisotropy

open access: yesAdvances in Materials Science and Engineering, 2021
The stress-strain characteristics of soil depend primarily on the previous stress history and stress path, thus related to both the stress magnitude and direction.

Thermal effects on one-way cyclic behaviour of clay-structure interface [PDF]

open access: yesE3S Web of Conferences, 2020
In energy geostructures, which exploit the heat in soil using earth contact elements, the interface is subjected to cyclic thermo-mechanical loads. Monotonic and cyclic constant-volume equivalent-undrained (CVEU) direct shear tests were performed on clay-

Degradation medium of agrocomplex - adhesive bonded joints interaction

open access: yesResearch in Agricultural Engineering, 2012
Research of degradation medium occurring in agrocomplex at the current interaction with bonded joints strength and lifetime is desired owing to the possibilities of bonding applications in this dynamically developing field. The bonding technology is used

Centrifuge model tests on large-diameter monopiles in dense sand subjected to two-way lateral cyclic loading in short-term

open access: yesSoils and Foundations, 2022
To evaluate the lateral resistance of rigid monopiles for wind turbines in dense sand under lateral cyclic loading, centrifuge model tests are performed, focusing on the base resistance and degradation of the soil resistance under two-way lateral cyclic ...

Centrifuge modelling of jacket foundation subjected to cyclic lateral loading in soft clay

open access: yesYantu gongcheng xuebao, 2018
The centrifugal model tests are carried out on a jacket foundation subjected to cyclic lateral loading in saturated soft clay to investigate the force and deformation characteristics of the jacket foundation under cyclic lateral loading from wind and ...

Cyclic AMP Receptor Protein from Yeast Mitochondria [PDF]

open access: yes, 1985
We have identified and characterized a cyclic AMP receptor protein in mitochondria of the yeast Saccharomyces cerevisiae. The binding is specific for cyclic nucleotides, particularly for cyclic AMP which is bound with high affinity (Kd of 10(-9) M) at 1 ...

Post-cyclic strength degradation behavior of soft clay under anisotropic consolidation and numerical simulation

open access: yesYantu gongcheng xuebao, 2017
Under the action of cyclic loading of waves, the strength degradation of the soft clay beneath the offshore structures will take place, which will weaken the stability of the upper structure.
