Stability analysis of Tang-e Hammam earthen rock-fill dam: numerical modeling and instrumentation data evaluation under varying reservoir conditions

Three-Dimensional Seepage Characteristics and Seepage-Control Performance of the Earth–Rockfill–Concrete Dam Connection at HS Reservoir

Connections between earth–rockfill and concrete dams are critical components of hybrid-dam seepage-control systems because material-stiffness contrasts and complex foundation conditions can create localized preferential seepage paths. Using HS Reservoir as a case study, this predictive design-stage assessment employed...

Geotechnical and Numerical Analysis of Slope Stability in Potentially Unstable Marly Formations

Scenario-based stability analysis of an embankment dam under rapid drawdown conditions

This study presents a comprehensive assessment of the transient slope stability of the Gavoshan embankment dam, located in western Iran, under a range of rapid reservoir drawdown scenarios. The analysis was performed using a sequential seepage–stability framework, in which transient pore pressures were computed in SE...

Numerical Simulation of Hydraulic Fracturing in Coal Reservoirs Based on a Damage–Seepage Coupled Model and Optimization of Perforation Parameters

Coal reservoirs exhibit strong heterogeneity and complex in situ stress conditions, and the initiation and propagation of hydraulic fractures are jointly controlled by reservoir geology and perforation design. A damage–seepage coupled numerical model was established on the COMSOL Multiphysics platform (Version 6.2) by...

Slope Stability Analysis of The Nipah Dam Embankment in Madura, Indonesia

Dam safety is essential for sustaining water supply, irrigation, flood control, and downstream community protection. Operational changes in reservoir levels may alter hydrostatic pressure, seepage conditions, and embankment stability, requiring comprehensive safety assessments. This study aimed to evaluate the slope st...

Field validation and engineering application of pressure-dispersed prestressed CFRP anchor cables for stabilizing toppling unstable rock slopes

This study evaluates the geomechanically efficacy and stability control of toppling-prone hazardous rock slopes subjected to multi-field coupled configurations, utilizing prestressed carbon fiber reinforced polymer (CFRP) anchor cables. A three-dimensional finite-element geomechanically model capturing sandstone hetero...
