Post-cyclic strength behaviors of undisturbed soft soils with different degrees of reconsolidation
Yantu gongcheng xuebao, 2021 The soft soil after cyclic loading is often in an intermediate state between unconsolidated and fully reconsolidated after a period of time, which can be described by the concept of degree of reconsolidation. At present, there are few studies considering

Strain Accumulation in Soft Marine Clay due to One-Way Cyclic Load with Variable Confining Pressure
Advances in Civil Engineering, 2021 The effect of variable confining pressure on the strain accumulation in soft marine clay was investigated to gain a better understanding of the deformation characteristic in the subgrade of pavements due to traffic loading. A series of variable confining

Cyclic Undrained Triaxial Strength of Sampled Sand Affected by Confining Pressure
Soils and Foundations, 1981 The effects of confining pressure on the cyclic undrained triaxial strengths of intact sandy specimens obtained by sand sampling methods were investigated. It was found that the ratio of cyclic deviator stress amplitude to initial confining pressure required to cause a certain value of cyclic axial strain amplitude at a certain number of loading cycle ...

Acoustic Emission Simulation on Coal Specimen Subjected to Cyclic Loading
Advances in Civil Engineering, 2020 The damage and failure state of the loaded coal and rock masses is indirectly reflected by its acoustic emission (AE) characteristics. Therefore, it is of great significance to study the AE evolution of loaded coal and rock masses for the evaluation of ...
