Reliability Analysis for Bypass Seepage Stability of Complex Reinforced Earth‐Rockfill Dam with High‐Order Practical Stochastic Response Surface Method [PDF]
Mathematical Problems in Engineering, 2019 Practical stochastic response surface method (SRSM) using ordinary high‐order polynomials with mixed terms to approximate the true limit state function (LSF) is proposed to analyze the reliability of bypass seepage stability of earth‐rockfill dam. Firstly, the orders of random variable are determined with a univariate fitting.

Numerical analysis of earthquake response of an ultra-high earth-rockfill dam
, 2013 Abstract. Failure of high earth dams under earthquake may cause disastrous economic damage and loss of lives. It is necessary to conduct seismic safety assessment, and numerical analysis is an effective way. Solid-fluid interaction has a significant influence on the dynamic responses of geotechnical materials, which should be considered in the seismic ...
