Effects of gravel columns on static and dynamic properties of sand: a laboratory investigation [PDF]
Scientific ReportsVibrated stone columns (composed of gravel in this study) are widely used for ground improvement. However, the composite behavior of sand–gravel composite columns (SGCC) under combined static and dynamic loading is not yet fully understood.

Measuring the cyclic compressional behaviour of soil under constrained lateral deformations [PDF]
Scientific ReportsWe propose a test procedure to quantify the response of dry sand to cyclic compressional loading under constrained conditions. The test procedure is designed to represent the response of sand layers to upward propagating P-waves during an earthquake ...

Effect of fiber-reinforcement on the mechanical behavior of sand approaching the critical state
Journal of Rock Mechanics and Geotechnical Engineering, 2022 Several types of ground improvement methods that employ fiber-reinforcement have been developed in recent years. A series of consolidated drained triaxial compression tests has been conducted here to examine the effect of short fibers on the mechanical ...

Influence of disturbance degree on the propped excavation stability in sandy soil in Shenyang, China
Underground Space, 2023 The stability of deep excavation is often investigated through numerical simulation. However, most constitutive models cannot take into account the influence of disturbance on soil response, especially for excavations in sandy soils.

Distribution patterns of final negative pressure in vacuum preloading
Yantu gongcheng xuebao, 2019 The distribution patterns of the final negative pressure are investigated in vacuum preloading under impeded bottom boundary in order to demonstrate the degenerated properties of vacuum degree and to determine the final vertical effective stress. Firstly,
