Geohazards and Large Geographically Distributed Systems
Geotechnical engineers play a critical role in managing the performance of large geographically distributed systems that are affected by geohazards such as earthquakes, floods, hurricanes, and landslides. Systems, such as water supplies, levees, and gas and liquid fuel supply networks, may cover thousands of km2 and be subject to many different ground response and geotechnical failure mechanisms. The geotechnical factors affecting system behavior have broad implications for life safety and regional economic stability.
The lecture will explore the geotechnical aspects of large system behavior during extreme natural events, starting with the performance of system components under extreme conditions of soil-structure interaction. The results of large-scale laboratory tests of underground pipeline response to ground rupture will be summarized. The results will be used to illustrate how such testing not only improves our understanding of complex, soil-structure interaction, but leads to improvements in geotechnical instrumentation and modeling of soil behavior. The geotechnical factors affecting regional system response to geohazards will be examined with reference to earthquake effects on the Los Angeles and San Francisco water distribution networks as well as hurricane effects on both the New Orleans levee system and Gulf of Mexico oil and gas pipeline supply network. The lecture will conclude with a discussion of advanced geographical information systems and remote sensing, which are important technologies for the assessment of geohazards and geotechnical factors influencing regional system performance.
