“…For Zipingpu dam rockfill, Xu et al (2012) assumed that the behaviour of samples with a lower density would represent that of the actual material and can be used for calibration of model parameters. While the void ratio of the actual material in the dam is 0.259, they used samples with void ratios in the range of 0.31 to 0.32 for triaxial testing.…”

Application of advanced bounding surface plasticity model in static and seismic analyses of Zipingpu Dam AbstractThe strong ground motion of the Wenchuan earthquake that hit the Zipingpu Dam in China in 2008 has provided an excellent benchmark to study the behaviour of large modern rockfill dams subjected to seismic loading. The performance of the dam during construction and prior to and after the earthquake loading has been recorded with good accuracy, and provides a reliable database to examine the reliability of available constitutive models and numerical methods in predicting the static and dynamic behaviour of embankment dams. In this paper, an advanced bounding surface plasticity model has been used in a series of numerical analyses to study the static and dynamic behaviour of Zipingpu Dam. The model can take into account particle breakage that may occur in monotonic and cyclic loading of rockfill materials. The material parameters required for the model are calibrated based on the results of available monotonic and cyclic triaxial tests. In the numerical procedure, the staged construction of the dam and the subsequent impounding of the reservoir are simulated, followed by dynamic loading. At each stage, the results of the numerical analysis are compared with in situ monitoring records of the dam. The results of the numerical simulation and the displacements measured after the earthquake are also compared with those estimated by two simplified engineering procedures that are routinely used in practice. The effectiveness and applicability of the simplified procedures to such a large dam subjected to an earthquake with a long duration is also discussed. procedures to such a large dam subjected to an earthquake with a long duration is also discussed.

Abstract. There was conducted the analysis of the results of numerical modeling of 3D stressstrain state of rockfill dams with reinforced concrete face (CFRD). It was obtained that tensile and compressive strength may be affected in the reinforced concrete face. Due to tensile strength failure the horizontal and inclined cracks appear in the face and due to compressive strength failure vertical cracks appear. From the point of view of tensile strength the most dangerous for the reinforced concrete face are not bending deformations but deformations of longitudinal extension arising from the dam body displacements. Therefore, stone in the dam body should have high shear strength, and stone distribution in the dam body by quality should be sufficiently uniform. It is recommended to construct high CFRD in several stages, because this creates longitudinal compressive force in the reinforced concrete face. High compressive stresses in the concrete face are typical for ultra-high dams located in narrow alignments. They act in a direction from the side to the side. To minimize the danger of vertical cracks development the intersection joints should be sufficiently wide (at least 2 cm thick) and should be compacted by the material with low deformation modulus in order to have a possibility of compensating compressive stresses.
