Soil nailing is a technique which used to reinforce and strengthen the existing ground conditions. This done by installing closely spaced, passive, structural inclusions known as nail into soil these nails helps improve overall shear strength of soil. The pullout resistance stress at grout-soil interface. soil-nail depends on many parameters. Among factors influencing resistance, degree saturat...

Abstract The Semmering Base Tunnel (SBT), with a total length of 27.3 km, is one the leading construction projects Baltic-Adriatic Railway Network. tunnel connects two federal provinces Lower Austria and Styria cuts through eastern part Alps. lot SBT 1.1-Tunnel Gloggnitz characterized by complex geological- hydro-geological architecture containing alternating competent geological structures, ma...

Grout is a cement-based material with high strength and workability that allowing it to be injected into small cracks or leaky areas. It usually used patch concrete holes, but may also fill voids under metal bases digging anchors. Furthermore, grout efficiently in the production process of semi-flexible pavement mixtures. The purpose this study characterize effect ingredients on their mechanica...

To make the bearing capacity tests safer and more affordable for prestressed high-strength concrete (PHC) piles, this paper proposes a reaction device anchor piles filled with core grout based on geometric mechanical characteristics of PHC piles. The proposed has advantages convenient construction, strong controllability connection quality low cost. In addition, pile will not experience prestre...

This research developed polymer grouts made from wastes such as fly ash, palm oil fuel and silica fume. The selected served an interlocking key between the StormPav covers a grout to seal gaps keys covers. Based on compressive strength workability of grouts, mix ratio resin ash = 1:1.00 was chosen grout, while 1:1.50 used form key. Mix ratios had 98.90 MPa 81.70 MPa, respectively, flexural 53.0...

Grouting is a common method of reinforcing fractured rock mass. The mechanical property grouted major aspect the reinforcement effect, which depends on geometry crack, angle (β) between load direction and other factors. Few studies have focused with bi-directional crack can reflect well grouting in stratum developed fractures. To explore effect mass, uniaxial compression tests were carried out ...
