The axial and lateral monotonic and cyclic behavior of helical pile foundations was investigated and new helical screw systems suitable for seismic loadings were developed. More than one hundred full scale field load tests were conducted on instrumented helical ...

<p>Fibre Reinforced Shotcrete (FRS) reinforced with macro-synthetic fibres has now been used to stabilize ground in underground mines and tunnels, and for slope stabilization, for over 10 years. Experience has demonstrated that macro-synthetic bres are capable ...

<p>The Western Australian School of Mines (WASM) has developed a facility for the static testing of full scale ground support elements. The test facility consists of several stiff steel frames used to support the sample and a screw feed jack is used to load ...

<p>Fibre Reinforced Shotcrete (FRS) is now used together with bolts for ground support in almost every underground metalliferous mine in Australia. Safety and economy have been the primary factors driving the widespread adoption of this system of ground support. ...

<p>The paper deals with the concrete lining behaviour at Serviceability Limit State (SLS) in order to evaluate the advantages that result from an optimized reinforcement based on the combination of rebars and fibers with respect to the crack behaviour of segmental ...

<p>New procedures to design cast-in-situ steel fiber reinforced concrete (SFRC) tunnel linings are briefly presented in this paper. The ductile behavior at ultimate limit stage of such cement-based structures is ensured by a suitable amount of steel fibers ...

Fibre reinforcement is a technology to improve the strength of soils used as fill in geotechnical structures. The properties of the fibre-reinforced sand are anisotropic because of the distribution of orientation of the fibres, which is characterised by a ...

<p>Traditional soil reinforcing techniques involve the use of continuous geosynthetic inclusions such as geogrids and geotextiles. The acceptance of geosynthetics in reinforced soil construction has been triggered by a number of factors, including aesthetics, ...

<p>The structural applications of Steel Fiber Reinforced Concrete (SFRC) have recently been increasing due to the improvement of material properties, such as in the material toughness under tension and durability. However, because the behavior of such structures ...

The contribution of fibers to the strength of fiber-reinforced soils is very much dependent on the distribution of orientation of the fibers. The fibers in the direction of largest extension contribute most to the strength of the composite, whereas the fibers ...
