<p>Measurements on back-fill grouting at Groene Hart Tunnel (GHT) are described and analysed. The research utilises TBM data, monitored grout pressures and measured rheological properties of tunnelling fluids. Grout injection strategy and vertical grout pressure ...

<p>The authors conducted a study of backfill practices in underground mines across Canada to assess the current state of backfill usage and to overview potential hazards associated with backfill practice, from preparation to transportation to placement. The ...

<p>The Geotechnical Engineering Bureau (GEB) provides earthwork and foundation engineering services for the design and construction of Departmental projects statewide. When subsurface explorations reveal that a project&rsquo;s underlying soils are soft or ...

<p>One of the most pressing needs for research in the geotechnical area is on the issue of the use of marginal soils (e.g. silts, soft rock, etc.) for fills and as backfill material for walls and bridge abutments. The lack of availability of higher quality ...
