Título del libro: Geotechnical Engineering In The Xxi Century: Lessons Learned And Future Challenges Título del capítulo: Land Subsidence and Associated Ground Fracturing in Urban Areas. Study Cases in Central Mexico
Land Subsidence; groundwater extraction; deformation; geological risk; urban development
Resumen:
Land subsidence affects urban areas with rapid development during the
last thirty years in central Mexico. The use of land represents a great
challenge for urban planning, and the issue is increased when
sustainable water resources management need to be added. Mexico
inhabitants rely on groundwater for about 60% of water supply.
Furthermore, the most of the cities are located in volcanic valleys
filled with fine and coarse grained sediments interbedded with
pyroclastic and volcanic materials. Three study cases are presented in
this work for comparative purposes: Mexico, Queretaro and Irapuato
cities. Compaction associated to groundwater depletion have caused
differential subsidence, ground fracturing and reactivation of faults,
depending on the local geological setting. Remote sensing monitoring
methods of land subsidence have proved to be useful tools to assess this
geological risk for urban planning, nevertheless more efforts need to be
addressed for the implementation of in-situ monitoring and other
techniques to prevent and manage damage to urban infrastructure.
