A Data-Driven Two-Layer Case-Based Reasoning Framework for Intelligent Deep Excavation Retaining Structure Selection Under Incomplete Information

In early-stage projects, incomplete geological data can affect the selection of retaining structures for deep excavations. This paper proposes an adaptive two-layer Case-Based Reasoning (CBR) framework to address this issue. First, a case database was constructed; feature interaction terms were incorporated into the si...

Pull-Out Performance of Rapid-Setting Sulphoaluminate Cement Grout for High-Strength Threaded Anchors in Water-Rich Sandy-Pebble Strata

Anchors constructed in water-rich sandy-pebble strata require grout systems that can maintain material continuity and transfer tensile force effectively before groundwater-related disturbance weakens the borehole interface. This study investigated a sulphoaluminate cement-based rapid-setting grout (SAC) for PSB high-st...

Progressive Failure Characteristics of Strain-Softening Subgrade Slopes Based on the Local Slip Point Safety Factor

In Southwest China’s mountainous areas, subgrade slopes are prone to strain softening and progressive failure under rainfall conditions. To clarify the failure mechanism and evaluate slope stability, this study adopts the displacement-isosurface-based local slip point safety factor method incorporating element stress–s...

Investigation of Mechanical Degradation and Microstructural Evolution of Red-Bed Soft Rocks Under Wetting–Drying Cycles

To clarify the water-sensitive deterioration mechanisms of red-bed soft rocks under repeated wetting–drying cycles, mudstone samples from two representative sites in the Sichuan Basin were investigated through multiscale experiments combining mechanical testing, X-ray diffraction (XRD), and scanning electron microscopy...

Dynamic analysis and protective structure optimization for clustered rockfall hazards triggered by the 2017 Jiuzhaigou earthquake: insights from 3D numerical modeling

Clustered rockfall hazards triggered by the 8 August 2017 Jiuzhaigou earthquake pose serious risks to infrastructure in mountainous areas. This study investigates the dynamic characteristics of clustered rockfalls and evaluates mitigation measures in the Zhongjijie Lake area. Field surveys were conducted to...
