To enhance the basic properties of backfill soil in high slopes and improve its safety and stability, through dynamic compaction treatment of the fillers, the reinforcement research was conducted for the first time by combining polymer grouting and field direct shear tests. Field direct shear tests...

Following a rice or wheat harvest, a large amount of crop residue (straw) is retained in fields. The straw is often incorporated into the soil in order to increase the soil organic carbon storage and to reduce soil erosion. However, it has become apparent that the incorporated straw can significantl...

This research is a laboratory study to improve the geotechnical properties of sandy soils. Concrete waste with a grain size of 1.2 to 1 inch was used for this purpose. The effect of using concrete waste at 0, 10, 20 and 30 weight percent on dry sandy soil in two loose and dense states was investigat...

Investigating the shear mechanical properties of non-penetrating jointed rock masses under various joint characteristics is of significant practical importance for underground engineering construction. This paper combines laboratory direct shear tests and numerical simulation methods to study the ma...

By using an improved DRS-1 high pressure direct shear test system, a series direct shear tests have been carried out under high normal stress and frozen-thawing conditions. Basic shear mechanical characteristics of the interface between the frozen soil and structure are summarized. Effects of normal...

Over prolonged service periods, reinforced gravel soil subgrades are susceptible to deterioration in interfacial mechanical properties due to the intrusion of fine particles. However, few studies focus on the interface of fine-grained polluted soil. To study the effect of fine particle content on th...

Landslides along bedding planes are a common type of rocky landslide, and the shear strength parameters of structural planes play a crucial role in the stability of bedding slopes. Previous tests of shear strength parameters for rock mass structural planes have mostly focused on laboratory experimen...

Prolonged cyclic water intrusion has progressively developed joints in the hydro-fluctuation belt, elevating the instability risk of reservoir bank slopes. To investigate its impact on joint shear damage evolution, joint samples were prepared using three representative roughness curves and subjected...

In this study, numerical experimentation was employed to investigate the influence mechanism of rock mass filling degree with rough cracks on the strength of the reformed rock mass. The diffusion pattern of slurry within rough cracks, characterized by JRC parameters, was analyzed. Uniaxial compressi...
