Effects on soil properties of future settlements in downtown Mexico City due to ground water extraction

Abstract

Water pumping from shallow aquifers under Mexico City causes large differential settlements. Consolidation modifies the mechanical properties of the subsoil, both static and dynamic. Approximate expressions to predict soil properties are proposed. A scenario for the distribution of settlements in downtown Mexico City suggests that the city's architectural heritage could be partly lost in a few decades. Seismic response analyses considering future soil properties show that seismic hazard distribution in the city will change. Some parts of the city including the downtown area and the Transition Zone, may become more vulnerable to high frequency earthquakes.
