Investigation of Failure Mechanisms and Performance Optimization of Channel Seepage Control Layers in Cold Regions Under Coupled Wetting, Drying, Freezing, and Thawing Cycles

To address the degradation of seepage-control linings and structural instability of water-conveyance channels under coupled wetting-drying-freeze-thaw conditions in cold regions, this study investigated rehabilitated channels founded on expansive mudstone in northern Xinjiang. A...

Water and salt migration model of solidified sulfate-contaminated soil by full solid waste cementitious materials

The limitations of the research on the water-salt migration of sulfate-stained soil using solid waste as the sole binding material, such as the difficulty in characterizing the hydration reaction products over time, were addressed in this study. The research focused on different...

A surrogate-driven optimization framework for thermal parameter inversion in hydraulic concrete structures

Thermal parameters are key inputs for numerical thermal analysis of hydraulic concrete structures. Under long-term service conditions, however, these parameters may progressively deviate from their design values because of environmental exposure, material deterioration, and compl...

Differential Assessment of Elevator Safety Risks in Urban Buildings Based on Regulatory Inspection Data

Elevators are essential infrastructure for ensuring the operational continuity of buildings and the safety of occupants. However, existing uniform elevator regulatory practices may not adequately capture the differences in safety risks among various building-use scenarios. This s...

Multi-Objective Optimization of Relief-Well Dewatering for Canals Under High Groundwater Levels Using NSGA-II and Entropy-Weighted TOPSIS

High groundwater levels can generate excessive uplift pressure beneath canal linings, causing heaving, cracking, and sliding failure. This study developed a multi-objective framework for relief-well dewatering design in a damaged reach of the headrace canal at the HLJ Hydropower...
