RISThree-Dimensional Soil–Water Characteristics Model of Expansive Soil Considering Swelling Effect
Publisher: ASCE
Abstract: In nature, expansive soil is generally in a state of swelling during rainfall, and its soil–water characteristic curve (SWCC) exhibits a three-dimensional space shape under the action of an increasing void ratio. In this ...
Decoupling Analysis Method for Rain-Induced Failure of Shallow Expansive Soil Slopes Considering Swelling and Strength Softening
Publisher: ASCE
Abstract: Rain-induced shallow failures in expansive soils often occur on gentle slopes with slope ratios of 1:2–1:6, resulting in highly complex stability issuesThis study established an equivalent theoretical model for the swelling ...
Evaluating the Effect of Brine on Water Absorption and Expansion of Red-Layer Mudstone in Central Sichuan Using Digital Image Correlation
Publisher: ASCE
Abstract: Red-layer mudstone is a typical expandable rock, that is, it easily expands and deforms in water. This study focused on the dynamic quantitative analysis of the mudstone hygroscopic process and development of strain caused ...
Changes in the Stability of a Superhigh-Deposit Slope Considering the Influence of Seepage Erosion
Publisher: American Society of Civil Engineers
Abstract: Rainfall can cause seepage erosion of the fine particles in soil (FPS) within the wide grading of particles present in a deposit slope, reducing its strength and eventually leading to a landslide. Unfortunately, there is ...
System Reliability Analysis of Soil Nail Walls against Facing Failures
Publisher: ASCE
Abstract: The facing design of soil nail walls against flexure, punching shear, and headed-stud tensile limit states has been rarely studied within the reliability-based design framework. This study presents reliability analyses of ...
