Abstract: On shallow tunneling, the assessment of risks in terms of surface settlements and tunnel face stability remains a huge challenge for engineers. In the aim to design conventional tunneling in an automatic sequenced process with risks analysis, a new 3D analysis software has been developed based on the finite element software CESAR-LCPC. This paper intends to present the features of the new...
Abstract: The underground section of the LRT T6 line will extend the public transport network towards the West of Paris and create new connections. The project consists of a 600m at-grade section followed by a 1500m long tunnel of 9.15m diameter, with two underground stations of 25m depth. Geologically the project is situated in a heterogeneous sedimentary sequence consisting of a series of marls,...
