Effects of Moisture Content, Compaction Energy, Particle Gradation, and Rainfall-Induced Wetting on the Compaction and Settlement Behavior of Coarse-Grained Soils in High Embankments: A Malaysian Case Study

High embankments constructed from coarse-grained soils play an important role in transportation and infrastructure development, particularly in projects requiring substantial elevation changes. The deformation behavior of such embankments is governed by the combined effects of particle gradation, moisture condition, co...

The Stability of Unsaturated Lateritic Slopes Under Rainfall Conditions Considering Shear Strength Variability

Rainfall-induced slope failures pose significant risks and economic impacts globally. This study investigates the impact of rainfall on the hydromechanical behavior and stability of unsaturated lateritic slopes, commonly found in tropical regions. By employing both experimental and computational analyses, this research...

Effect of the Degree of Saturation on the Behavior of a Single Sand Column in Clay

Researchers have extensively studied the Use of granular piles (sand columns) as a ground improvement technique under fully saturated conditions, but have paid limited attention to the influence of the unsaturated zone, which reflects soil conditions in arid and semi-arid regions. However, their behavior in partially s...

Slope Stability Analysis of Steep Tropical Volcanic Soil Slopes Stabilized by Moisture-Controlled Compaction

Landslides on steep slopes composed of tropical volcanic soils constitute a major geotechnical hazard because intensive weathering and variations in water content can substantially affect soil shear strength and slope stability. This study evaluated the effectiveness of moisture-controlled compaction in improving the s...

Influence of petrochemical contamination on the geotechnical behavior, shear strength characteristics, and compressibility indices of sandy clay soil

One of the most important geo-environmental issues is the contaminated soils in the construction industry which are caused by the contamination of petrochemicals. In contrast with previous studies which evaluated individual soil properties separately, this study presents an integrated experimental evaluation of index p...

Study on the mechanical properties of coarse-grained soils with different fine-grained contents under freeze-thaw cycles

This research analyzed the impact of fine-grained content on the mechanical characteristics of coarse-grained soil in the river valley region of southeastern Xizang under freeze-thaw cycle circumstances via indoor tests, and modified the Duncan-Zhang model based on the test results. A total of six different coarse-grai...
