Dynamic Finite Element Analysis of Young Shotcrete in Rock Tunnels

The problem with shotcrete on rock subjected to vibrations has previously been studied in place and through numerical modeling. Within the present project, an elastic finite element model is presen ...

Cracking of Concrete Buttress Dam Due to Seasonal Temperature Variation

The largest and most important hydropower dams in Sweden are concrete buttress dams. These consist of a large number of concrete monoliths formed by a frontplate with a supporting buttress. Cracks ...

A coupled multi-physics model for creep, shrinkage and fracture of early-age concrete

The behaviour of concrete at early-age is complex and involves several physical fieldssuch as temperature, moisture and deformations. In this paper a hygro-thermo-chemo-mechanicalmodel for the anal ...

Numerical Simulations of Restrained Shrinkage Cracking in Glass Fibre Reinforced Shotcrete Slabs

Modern tunnels in hard rock are usually constructed by drill and blast with the rock reinforced by shotcrete (sprayed concrete) in combination with rock bolts. The irregular rock surface and the pr ...

Shrinkage cracking of thin irregular shotcrete shells using multiphysics models

Shotcrete (sprayed concrete) is commonly used to support tunnels in good quality hard rock. Including a drainage system often results in end-restrained sections of shotcrete, which have created pro ...

Design of bolt anchored reinforced shotcrete linings subjected to impact loadings

Shelters and some drifts in mines should be designed for rock burst induced by detonations. Absorption of released momentum is studied experimentally for both steel fibre and mesh reinforced shotcr ...
