Abstract:

The objective of this research was to contribute to the development of rational design approach in the use of spiling reinforcement in underground construction. By investigating the mechanisms of spiling reinforcement, through physical and numerical models, its contribution as an immediate stabilization as well as its contribution to the permanent stabilization of a circular tunnel were ascertained. From case histories and other investigations, were spiling had found application, the rock mass characteristics were assessed. On the basis of physical model laws, and the rock mass characteristics a suitable modeling material was developed. A model test chamber for three dimensional studies, and an instrumentation system were designed. Physical model tests with and without spiling reinforcement were performed. A numerical model was developed to aid in the interpretation of the physical model test results.
