Theodoros Triantafyllidis

Theodoros Triantafyllidis (born January 10, 1954 in Patras ) is a Greek-born German civil engineer specializing in geotechnical engineering and a university professor at KIT .

Triantafyllidis attended high school in Patras until his Abitur in 1972 and after a preliminary semester studied civil engineering there at the TH Karlsruhe (today's KIT) with a diploma in 1979 with a specialization in structural engineering. He then worked as a research assistant at the Institute for Soil Mechanics and Rock Mechanics with Gerd Gudehus until 1989 and received his doctorate in 1984 and habilitation in 1989. He then worked in the construction industry, initially as a group leader for measurement and control technology at Bilfinger & Berger in their head office, and from 1991 to 1993 as head of the civil engineering department at Leighton-Brückner Foundation Engineering Ltd. in Hong Kong and Thailand and from 1994 to 1998 as head of the central technology department at Brückner Grundbau. His projects included the construction pits at Potsdamer Platz in Berlin and for the Lehrter train station. In March 1998 he became professor for foundation engineering and soil mechanics at the Ruhr University Bochum and in 2007 head of the institute for soil and rock mechanics at the TH Karlsruhe as successor to Gudehus.

He dealt with excavation pits, soil dynamics (e.g. dynamics of railway tracks and the effects of high-speed trains via ground vibrations on nearby buildings, dynamic coupling of foundations via the ground, cyclical triaxial tests for earthquake hazard from foundations of nuclear reactors) and numerical modeling and methods (e.g. B. Boundary element method), special civil engineering and tunneling. At Bilfinger, in addition to special foundation engineering projects (such as excavation pits with bored pile walls, sealing walls, large bored piles), he was mainly concerned with measurement technology, such as determining the minimum diameter of HDI columns with hydrophones . He also developed a tried and tested method for compacting pre-compacted household waste dumps and a removable grouting anchor (tested on the construction site of the Lehrter train station).

Outside Germany, he is a member of the chambers of engineers in Hong Kong and Greece.
