S13 Seismic Aspects of Large Embankment and Concrete Dams
Description:
The session on ¡®Seismic Aspects of Large Embankment and Concrete Dams¡¯ will be organized in cooperation with the Committee on Seismic Aspects of Dam Design of the International Commission on Large Dams (ICOLD).
As very few large concrete dams have been damaged during an earthquake and since the few dynamic model tests carried out with dam models up to rupture are not really representative, there are still considerable uncertainties about the behaviour of a dam under the maximum credible earthquake (MCE) or safety evaluation earthquake (SEE). It may be expected that in the coming years further developments are made, e.g., in the following fields:
- inelastic earthquake behaviour of dams under strong ground shaking of MCE/SEE;
- dam design to resist MCE/SEE including development of simplified method for the assessment of the dynamic stability of cracked concrete dams and the dynamic slope stability of embankment dams;
- efficient seismic strengthening of existing dams;
- seismic hazard assessment and refinement of seismic dam design criteria;
- short-term behaviour of mass concrete, RCC and embankment dam materials (dynamic tensile strength of mass concrete, tensile strength in lift joints and contraction joints);
- simulation of effect of fault movements in dam foundations on behaviour and safety of dam;
- seismic safety of concrete face rockfill (CFR) dams and roller compacted concrete (RCC) dams;
- seismic design and safety of underground structures (tunnels, caverns, shafts);
- hydromechanical equipment (gates, penstock, valves, bottom outlets, intake structures etc.)
- dynamic rock slope stability in reservoir area, triggering of landslides and rockslides (mass movements) in reservoir area;
- foundation stability of dams during earthquakes, etc.
Abstracts and papers on the following topics are invited and shall be presented and discussed at the Conference:
- Seismic safety of existing dams;
- Effects of recent earthquakes on dams and strong motion data;
- Reservoir-triggered seismicity;
- Seismic hazard assessment at dam sites;
- Seismic design criteria for large dams;
- Faults in dam foundations;
- Seismic aspects of underground works;
- Seismic aspects of slope stability of embankment dams and slope stability in reservoir region;
- Seismic aspects of roller compacted concrete and concrete-faced rockfill dams
- Seismic aspects of diaphragm walls and grout curtains in dam foundations.
