| Abstract | As the earthquake event occurred in Chiangrai, northern of Thailand many types of structure affected and damaged. Large infrastructure, especially dams were also affected by the earthquake and made people concerned about the dam safety. One of the large dam with more than 50 m height and located about 20 km from earthquake epicenter is Mae Suai dam. The dam consists of concrete gravity spillway at the middle section and earth embankment dam at both left and right abutment. According to the dam is a composite dam between concrete and earth embankment dam that have different natural frequency. When earthquake occurred concrete and earth embankment will move separately can cause a gap between the interfaces and lead to occurred leakage through the gap. During the earthquake event pore pressure and leakage through the earth embankment section increased rapidly and reduce with time. Not only the main shock of earthquake, after shock also caused the increased of pore pressure and leakage. Behavior of interfacial cracks in concrete-embankment dams is still unclear. Since the problem has three dimension effects, normal two dimensions FEM software are not proper and three dimensions FEM software are also complicate to find the interfacial parameters. Shaking table physical model tests was conducted to simulate the behavior of interfacial cracks in concrete-embankment dams during earthquakes. The results show the amplification of acceleration in embankment section with height, large differential movement at the top part of the dam between concrete-embankment section and also pore pressure develop during shaking. Pore pressures were measured due to impounding water after shaking |
