Conservation of monuments and historic sites is one of the most challenging problems facing modern civilization. It involves various cultural, humanistic, social, technical, economical and administrative factors, intertwining in inextricable patterns. The complexity of the topic is such that guidelines or recommendations for intervention techniques and design approaches are difficult to set. The Technical Committee on the Preservation of Monuments and Historic Sites (named TC19) was established by the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE) in 1981, is supported by the Italian Geotechnical Society (AGI), and renamed TC301 in 2010. Geotechnics and Heritage, collects relevant case histories on the role of geotechnical engineering in the preservation of monuments and historic sites, and is an addition to the Proceedings of the two International Symposia organized by the Committee in Napoli in 1994 and 2013. The contributions in the book prove the significant role geotechnical engineering plays in conservation of historic building and monuments.

Piled foundations are generally designed using empirical methods, in particular the traditional capacity based approach on which the majority of codes of practice are based. However in recent years the analysis of pile groups and piled rafts has undergone substantial development in the light of new research and the mechanisms for the interactions between piles, soil and rafts or caps have been largely clarified. Paradoxically, with relatively large piled rafts it has been found that a design based on the criterion of serviceability, with the limitation of absolute and/or differential settlement, not only allows a more rational and economical design, but is also simpler and more reliable than one based on the traditional approach.This book provides an overview of present design practice of piled foundations, under both vertical and horizontal loads, and then a presentation of recent advances in the analysis and design of piled rafts. Altogether it forms a thorough guide to the design and analysis of efficient and effective piled rafts, and it also serves as a useful design handbook for traditional pile foundations.

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.

All the traces of historic heritage are a fundamental part of our environment and reward us in the form of cultural enrichment, with the ability to have a positive effect both on our lifestyle and economy. Therefore, the preservation of ancient monuments, historic towns and sites has increasingly drawn the attention of public opinion, governmental agencies as well as consultants and contractors. This interest must be however carefully controlled and directed, since the conservation of monuments and historic sites is one of the most challenging problems of our age. Careless attempts at preservation can be detrimental not only to their iconic value (formal integrity), but even to their structural characteristics and the materials they are built with (material integrity).Geotechnical Engineering for the Preservation of Monuments and Historic Sites collects one opening address, four special lectures and 82 contributions from all over the world, giving a unique sample of the geotechnical problems to be tackled, the solutions currently being proposed, and the strategies being carried out to preserve the overall integrity of monuments and historic sites. It is clearly apparent that differences exist around the world not only in terms of the characteristics of the monuments or sites to be preserved, but also in the approaches adopted to achieve this aim. Hence, no unique solution is available to the geotechnical engineer dealing with the delicate structures and sites that represent our cultural heritage, and knowledge of previous experiences may be a unique guide in any technical decision-making process.

The complexity of the topic is such that guidelines or recommendations for ntervention techniques and design approaches are difficult to set.

Well-documented, exemplary case histories highlight concepts of preservation, integrity, cultural heritage, dynamic identification techniques and techniques for long-term monitoring of historic towers, as well as provide examples of appropriate intervention measures.The book will be of interest to professionals and academics in the wider fields of civil engineering, architecture and cultural resources management, and particularly those involved in art history, history of architecture, geotechnical engineering, structural engineering, archaeology, restoration and cultural heritage management.
