About this document
Impact of Face Pressure on Tunneling Settlements by Senthil Nath is a document available to read on EtoBox.
This document summarizes a study that uses numerical modeling to analyze the influence of tunnel boring machine (TBM) face pressure on surface settlements during mechanized tunneling. The study uses 3D finite element analysis to model excavation with an earth pressure balance (EPB) TBM and variables like TBM face pressure, ground properties, and tunnel depth. It finds that increasing face pressure decreases surface settlements by restricting tunnel face deformation and pre-convergence. The modeling aims to
