Interaction between foundations and underground excavations: The beauty of analytical solutions

Speaker: Prof. Eduardo Alonso (UPC Barcelona Tech, Spain)

Biography:  

Eduardo Alonso has been Professor of Geotechnical Engineering at the Civil Engineering School of UPC since 1986. He is a past Dean of the School and a past Vice-Rector for research at UPC. His main research interests have focused on the stochastic analysis of soil heterogeneity, unsaturated soil mechanics, rockfill mechanics, dam engineering, coupled thermo-hydro-mechanical analysis and some chemo-mechanical interactions. He has maintained a special interest in landslide phenomena, a subject which involves the disciplines of engineering geology, rock mechanics and soil mechanics.

Recently he has contributed to the development of a computational technique, the Material Point Method, capable of addressing the static and dynamic aspects of landslide instability. He has lectured in many countries and he has also acted as a consultant on a variety of geotechnical engineering projects in several countries. He is member of the Royal Academy of Engineering of Spain and he is the current editor of ICE journal Géotechnique. Past honorary lectures include Coulomb, Buchanan, Sowers, Croce, Heim, Kezdi, Rocha and BGA Touring lectures.

Introduction to the Lecture:

The Lecture is inspired by the construction of a railway tunnel line very close to the well known Sagrada Familia temple in Barcelona (A UNESCO world heritage monument). The presentation discusses the available procedures to protect existing structures against deformations induced by tunneling. Some analytical solutions for concentrated loads in a half-space and the presence of volume loss or volume increase at any point serve to develop generalized procedures to analyze in detail the three-dimensional interaction between tunneling and compensation grouting on pile foundations.
