ABSTRACT
Based on the equivalent viscoelastic model, the dynamic characteristics of dam, panel and diaphragm wall of concrete faced sandy gravel dam built on deep overburden at Chahanwusu, Xinjiang are calculated and analyzed. The results show that dynamic deformation of the dam along the river increases with the increase of the dam height. The calculated maximum permanent seismic subsidence is about 0.14% of the height of the sandy gravel dam and the thickness of the overburden layer. The maximum stress along slop of panel is located at the middle of the dam bottom, and central of dam crest has the largest deflection. The diaphragm wall will not be damaged under the earthquake. This paper can provide guidance for the construction and design of extra high or high faced sandy gravel dam on deep overburden layer.
