Research on Settlement Prediction and Control of Lock Floor Concrete Pouring Construction

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
As the core structure of inland waterway hubs, lock engineering’s structural safety directly affects navigation efficiency and life cycle benefits. With the advancement of “quality engineering,” construction accuracy requirements have evolved from traditional strength control to three‐dimensional spatial precision, particularly for floor slab elevation,

A Novel Permutation Entropy–Based Method for Assessing the Stability of Seawalls on Soft Soils

Structural Control and Health Monitoring, Volume 2026, Issue 1, 2026.
Evaluating the stability of seawalls constructed on soft soils is critical but challenging. Traditional methods often depend on whether settlement velocity exceeds predefined thresholds, which can overlook subtle settlement fluctuations and may be less adaptable to varying construction and environmental conditions.

Localized Energy Absorption through LaB6 Surface Modification of PA12 Enables Enhanced Tensile Performance in Diode Laser PBF‐LB

Chemistry–Methods, Volume 5, Issue 12, November 2025.
LaB6 surface modification of PA12 enables efficient NIR diode laser PBF‐LB processing, with enhanced tensile strength and tailored microstructures achieved at minimal additionaly energy. By reducing the need for high filler content, this approach expands the options and performance levels of advanced industrial‐grade polymer additive manufacturing. The

Strength, Hydraulic, and Microstructural Characteristics of Expansive Soils Incorporating Marble Dust and Rice Husk Ash

Advances in Civil Engineering, 2021
Expansive/swell-shrink soils exhibit high plasticity and low strength, which lead to settlement and instability of lightly loaded structures. These problematic soils contain various swelling clay minerals that are unsuitable for engineering requirements.

Improving Constitutive Modelling of Soft Organic Clays With New Experimental Insight

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 18, Page 4480-4501, 25 December 2025.
ABSTRACT The engineering response of soft organic clays is controlled by anisotropy, stress history and the nature of organic matter. The behaviour of these soils has been investigated extensively over compression triaxial paths, and models are available to successfully reproduce available experimental observations. However, open questions remain about

Modelling Wetting Collapse, Failure and Deposition of an Unsaturated Slope With Material Point Method

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 49, Issue 18, Page 4526-4551, 25 December 2025.
ABSTRACT The paper presents the modelling of unsaturated soils with the material point method (MPM), including the effect of wetting leading to the loss of strength and the volumetric collapse. The elastoplastic Clay and Sand Model (CASM) extended to unsaturated conditions, formulated in terms of Bishop's stress and suction, has been implemented in an ...
