GTSym Online Lecture Long-term investigation of tunnel linings: A study case from CERN Friday, 1 July 17:00 to 18:00 hrs (UTC+3 EEST)

The long-term performance of tunnel concrete linings through innovative monitoring technologies using distributed fibre optic strain sensors has been a topic of particular interest in the tunnelling industry. Dr. Di Murro will be presenting on the unique setup that was developed at the European Centre for Nuclear Research (CERN) in Geneva, focusing on the long-term […]

1. We go down Athens underground. (Athens centre, moving around on foot)
Saturday 13 May, 2023

How many surprises can the Athens underground have in store for its visitors? The stroll will start from underground shelters and detention areas of the German Kommandatur, remnants of the 2nd World War in Athens. Then, we will take the steps that start off under a timeworn trap door on the side of a road or hidden away in a sidewalk flower–bed, that will lead us in a different, forgotten underground area of the city! For hundreds of years, underground pathways have been used for various and mysterious purposes. Some say that all underground pathways are interconnected although there is no proof of this. Nevertheless, the allure of an unknown world is always there, beneath the ground we walk on. We lift up the antiquated hatch and descend the stone steps. In the catacomb, we come across tunnels of ancient aqueducts, roman baths and byzantine crypts. The Athens river is also found hidden below the ground, running in old galleys under the most central streets of Athens – we can hear the cars passing over our heads!

We invite you to discover together the hidden secrets of our city!

Scientific theme: underground constructions of the 19^th and 20^th century.

Duration: Maximum of 4 hours.

Detailed program:

11.00 Meeting outside Metro Station Panepistimio

11.30 Memorial Site (Korai Street). Two-level underground shelter below the Mansion of Ethniki Insurance Company.

13.00 Catacombs of the Russian Church (Filellinon Street). Inside the catacombs a tunnel and a shaft from ancient Peisistratus aqueduct, ruins from roman baths and crypts of the Byzantine order of Likodimos -11^th century.

14.00 Ilissos River (area of Panathenaic Stadium). The buried riverbed of Athens river Ilissos.

Cost per person : 35,00 €

*limited participation on a first come first served basis. In case participants are less than 20, the respective event will be cancelled and a refund wil be given.

Professor Kyriazis Pitilakis

Professor Kyriazis Pitilakis has more than forty years of intensive academic, research and professional experience in civil, earthquake and geotechnical engineering. Vice-President of the European Association of Earthquake Engineering (EAEE), ex- Chairman of the Technical Committee “Geotechnical Earthquake Engineering andAssociated Problems” (TC203) of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE), and past President of the Greek Society of Earthquake Engineering. He is presently Professor Emeritus in Aristotle University, Thessaloniki, Greece and since 2019 visiting Professor in Tongji University, International Laboratory of earthquake Engineering (ILEE), Shanghai, China.

Coordinator and scientific responsible of numerous European research projects, namely EUROSEISTEST and SYNER-G, he has a long experience in European research activities in earthquake engineering, geotechnical engineering, vulnerability and risk assessment of civil engineering structures, infrastructures and lifelines. According to the recent Stanford classification he is among the top 10 leading researchers in Civil Engineering in Greece, and among the top 10 leading international researchers in specific topics like Soil Dynamics, Engineering Seismology and Geotechnical Earthquake Engineering.

Chairman of several international conferences including the 16th European Conference of Earthquake Engineering, Thessaloniki 2018 and invited keynote lecturer in many International Conferences. Author of more than 650 scientific papers (h-factor 57) published in peer review scientific journals, and conference proceedings, author and co-author in several books, editor of four books published in Springer Editions, all in relevant subjects of earthquake engineering, seismic risk and geotechnical earthquake engineering. Professor Kyriazis Pitilakis is founder and coordinator of EUROSEISTEST, a large scale experimental facility in earthquake engineering, soil dynamics and engineering seismology that is unique in Europe and worldwide. He supervised more that 30 PhD thesis and numerous of his students hold academic positions in Greece and worldwide.

Professor Kyriazis Pitilakis is strongly involved in the ongoing revision of EC8 (Part 1-Seismic Actions and Part 5-Seismic design of foundations, retaining structures, soilstructure interaction, liquefaction, slope stability and underground structures), while he has been international expert for the revision of other seismic codes worldwide.

He is member of the editorial advisory board in Springer editions (Geotechnical, Geological and Earthquake Engineering), member of the editorial board and reviewer of numerous scientific journals and member of many international societies in earthquake and geotechnical engineering.
