1. Analytical and numerical approaches to estimate peak shear strength of rock joints
Sammanfattning : In Sweden, there exists a large number of dams. Many of them are founded on rock masses normally affected by the presence of sub-horizontal rock fractures, which makes sliding along rock joints under the dam foundation one of the most critical failure mechanism. LÄS MER
2. Rock grouting design: Rheological aspects and radial flow visualizations with ultrasound
Sammanfattning : The rheological properties of cement-based grouts play a crucial role indetermining the final spread in grouted rock formations. In rheological terms,cement grouts are known to be complex time-dependent yield stress fluids,but their steady flow behavior is often described by the simple Binghamconstitutive law. LÄS MER
3. On the measurement and application of cement grout rheological properties
Sammanfattning : The rheological properties of cement-based grouts play a key role in determining the final spread in grouted rock formations. Rheologically, cement grouts are known to be complex thixotropic fluids, but their steady flow behavior is often described by fitting the simple Bingham constitutive law to flow curve data. LÄS MER
4. Peak Shear Strength of Rock Joints – Towards a Methodology for Prediction Based on Field Data
Sammanfattning : The rock joint shear strength at field scale is an important design parameter and remains a challenge for rock mechanics engineers. In Sweden, there exist a large number of concrete dams that are founded on rock masses which in many cases contain sub-horizontal rock joints. LÄS MER
