Abstract Concrete Facing Rockfill Dam (CFRD) is a popular type of dam for hydropower plant due to its relatively good stability than others. However, CFRD have potential technical issue concerning seepage and leakage as it has thin impermeable layer. In this study, against was evaluated by finite element simulation. facing layer foundation were assumed undergo permeability coefficient (K) incre...

In the context of dam deformation monitoring, prediction task is essentially a time series problem that involves non-stationarity and complex influencing factors. To enhance accuracy predictions address challenges posed by high randomness parameter selection in LSTM models, novel approach called sparrow search algorithm–long short-term memory (SSA–LSTM) has been proposed for predicting concrete...

As a new type of dam, roller compacted concrete dam (RCCD) develops very fast in recent years. Deformation plays an important role in the RCCD’s safety. The deformation of RCCD is influenced mainly by three parts: water pressure, temperature and time effect. As to any of the three parts, there are many factors. Therefore, the deformation of RCCD is a complicated system. The least squares suppor...

This study aims at determining the critical seismic intensity at which cracks are expected to develop in a concrete arch dam. This intensity is referred to as crack initiation intensity. The crack initiation intensity measure implies that earthquakes with the intensity measure higher than this value are expected to induce cracks in the arch dam. This quantity is an indicator for seismic evaluat...
