SEISMIC EVALUATION AND RETROFIT OF WATER SUPPLY LIFELINES

 

Abstract

Professor O'Rourke will present the salient features of the MCEER research program focused on the seismic evaluation and retrofit of the water supply lifelines. The presentation will deal with the performance of the Los Angeles Department of Water and Power (LADWP) and Metropolitan Water District (MWD) water supply systems during the Northridge earthquake, and the implications of this performance with respect to lifeline design, system operation, and emergency response in future earthquakes. The talk will feature advanced uses of GIS. It will also show how the distribution pipeline network of LADWP has been used as a regional sensing system to evaluate seismic hazards. The influence of ground failure on lifeline performance will be covered with explicit reference to liquefaction and ground lurching effects. The presentation will also address the use of fiber reinforced composites to strengthen the welded slip joints of critical water trunk lines, and show how these technologies are being developed and implemented by academic/industry partnerships organized through MCEER.
