Abstract

Within the Belgian research programme for geological disposal of radioactive waste an experimental gallery was excavated to host a large scale heater test in Boom Clay. In this project, a gallery crossing was realised and the gallery has been excavated by a roadheader under the protection of a shield. The combination of geotechnical and (future) thermal loading of the concrete lining resulted in the use of several compressive materials. Geotechnical monitoring was carried out during construction.
