Experimental study on the reinforcement performance of unloading-damaged mudstone by microbial grouting

<title>Abstract</title> To address the structural deterioration and water-induced swelling of mudstone caused by unloading damage during foundation excavation, grouting reinforcement tests using MICP and volcanic ash-assisted MICP were conducted. Mudstone specimens with unloading...

Numerical Study on the Stability of a Riprap for Submarine Cables and the Protective Solution Under Waterflow Incidence

This study presents a numerical investigation into riprap stability for submarine cable protection under high-speed incident waterflow conditions. A coupled CFD-DEM numerical model, implemented within the ANSYS 2024 R1 platform, was developed and validated against controlled labo...

A Comparison Study on the Dynamic Response of Rectangular and Circular Pile–Slab Retaining Walls Against Rockfall Impact

Abstract Pile–slab retaining wall (PSRW), as an innovative passive protection structure for mitigating rockfalls, has been extensively utilized in the western mountainous regions of China. A typical PSRW is composed of reinforced concrete piles, concrete slabs, and a soil cushion...

Rainfall-Pattern-Dependent Regulation of Hillslope Erosion by Vegetation Conservation Measures in Subtropical Hilly Farmland: A Multi-Method Analysis

The Southern Jiangsu hills region is located within the Yangtze River Delta Ecological Barrier. Soil erosion poses a threat to the development of commercial forests and the water quality of Lake Taihu, making it urgent to quantify the mechanisms by which vegetation and rainfall r...
