ENTPE Project Scope

ENTPE Organisation        ENTPE Key Personnel

DGCB/ENTPE’s role in the NeTTUN project focuses on the work package “Impact of tunnelling on surrounding structures”. The two principal investigators at DGCB/ENTPE are Prof K.K. Wong and Dr D. Branque. They have developed for the last 15 years research in the domain of underground works using both experimental and theoretical approaches.

Within the framework of NeTTUN, DGCB/ENTPE contributes a reduced-scale model of earth pressure balanced shield, unique at the international level. With this experimental device, DGCB will carry out extensive research and development activities with the objective to analyse, to improve the understanding and to quantify the phenomena of interaction between the TBM and different types of foundations (shallow footings or piles) of neighbouring structures. These tests will also serve to analyse the efficiency of different protection measures.

Numerical simulations and work site monitoring will be performed in parallel with all these tests.
