Rockfill Dam With Clay Core In Manla Multi-Purpose Water Project Study On Dynamic Characteristics Of The Dam Material And Analysis On Its Seismic Response

The earth dam had in the past usually been under severe impact during violent earthquakes. The rockfill dam with clay core in Mania Multi-Purpose Water Project is constructed in high intensified areas, it is therefore imperative to have a thorough knowledge about the earthquake resistance of the dam.By virtue of the design features of the Mania Dam, this paper studies the dynamic characteristics of the dam materials. By comparison with other similar projects, it presents a Curve for Dynamic Characteristics of Clay Core Materials and Rockfill Materials, makes analysis on the dam's plane dynamic response by Finite Element Method, calculates the dam's seismic acceleration, the dynamic shear stress of the rockfill, and the dynamic stress of the cutoff wall in the overburden layer. Through analyzing the above calculation results, it is believed that the Mania rockfill dam with clay core is highly capable of earthquake resistance.
