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...

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...
