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...

The Design and Construction of Grouting against Water Ingress in the Headrace Tunnel for the Uma Oya Project, Sri Lanka
Abstract: The 15.2km long headrace tunnel (HRT) is a key component of the Uma Oya Multipurpose Development Project (UOMDP). The HRT takes water from Dyraaba Dam to the pressure shaft that feeds the power house. The excavation of the major 4.30m diameter headrace tunnel is done by using a double shield TBM. This is the first use of a TBM in Sri Lanka. High water...
