Multi-Dimensional Evaluation of Tunnelling Pre-Grouting Methodology Based on Excavation and Overhead Costs...
Abstract: Water drawdown due to water ingress is a probable issue in tunnelling processes. This makes serious problems including ground settlements, environmental problems, increasing costs, excavation hazards, and several executive difficulties. In this paper, using measured data, data investigation, probabilistic and sensitivity analysis, machine learning methods, curve fitting, and several numerical...
