This book contains the invited lectures presented at the 3th International Symposium on Geotechnical Engineering for the Preservation of Monuments and Historic Sites (IS NAPOLI 2022, Naples, Italy, 22-24 June 2022). It collects the opening address, the third Kerisel Lecture, four keynote lectures and eleven panel lectures, and provides a broad impression of 1. the current state of knowledge and 2. the techniques used worldwide for the preservation of built heritage. When confronted with structures relevant to local and global history, there is only one way to select the best possible conservation solution: the multidisciplinary approach. Therefore, the invited speakers have been selected with different pertinent skills, to represent this complexity from the points of view of geotechnical engineers, structural engineers, architects and conservation experts.
The book will be useful to researchers, practitioners, administrations and all those working or interested in the preservation of built heritage.

Filomena de Silva has deeply studied the effects of the dynamic soil-foundation structure interaction (SFSI) on the response of ideal structures and case-studies, through analytical tools and numerical simulations performed by following the sub-structure method and by modelling the full SFS system during her PhD under the supervision of prof. Francesco Silvestri,. She has been hosted by the Geotechnical Team of the Aristotle University of Thessaloniki (Greece) and worked with prof. Dimitris Pitilakis who has a deep experience on experiments on SFSI. She has again collaborated with him in the 2018 EU project Seismic Impedance for Soil-structure Interaction From On-site tests, SISIFO funded by the HORIZON2020-supported program SERA (Seismology and Earthquake Engineering Research Infrastructure Alliance for Europe). On such a topic she has been the co-supervisor of the M.Sc. thesis of Chiara Amendola, awarded with the prize on the application of geophysics to earthquake engineering, sponsored by the National Institutes OGS and CNR and dedicated to Marco Mucciarelli.
Thanks to her expertise on SFSI, she gained a fellowship at the University of Leeds to work on the effects of the soil on the seismic fragility of tunnels in the frame of the international EPSRC project Shaking Tunnel Vision, whose results were selected for the Geotechnique symposium in print 2019.
Lucia Mele is a Research Fellow at University of Napoli Federico II, Italy. In 2017 she started a PhD course in the framework of the European Project LIQUEFACT, focusing the attention on improving the basic understanding of liquefaction behaviour of sandy soils and studying several techniques to mitigate liquefaction risk. She mainly worked in laboratory, performing monotonic and cyclic (triaxial and simple shear) tests. She spent two months in Tokyo University (Japan), where she studied in depth the effect of non-saturation on liquefaction resistance. She took part to several conferences presenting the results of her research to scientific community.
