The adhesive strength between a thin spray-onliner(TSL) and rock is an important property controlling the designandperformanceofTSLrocksupportsystems. The advantages and disadvantages of various adhesion test methods used by the coatings, microelectronics and concrete industries with respect to TSLs are discussed. A suggested test method for TSL materials is presented, which is based on direct pull-off of an elevator bolt that is attached to a liner with strong epoxy. To interpret the test results correctly, the effect of the liner thickness on adhesive strength must be assessed. This was shown experimentally and was supported by an analytical solution. The adhesive strength is inversely proportional to the square root of the liner thickness. Tests were performed using Tekflex as a liner material, which was applied to concrete or granite substrates.

Creep behaviour investigation of a thin spray-on liner Güner, Doğukan; Öztürk, Hasan (Elsevier BV, 2018-08-01) Thin spray-on liner (TSL) is a fast-setting multi component polymeric material applied on a rock surface with a thickness of 2-5 mm. TSLs are primarily used as an areal support element in a support system that also incorporates rock bolts. Different laboratory and field tests were performed to understand the support performance of the TSL for underground design. The research described in this paper presents laboratory studies of the tensile creep behaviour of a cement based TSL for the first time in the lit...
Obtaining soil-water characteristic curves by numerical modeling of drainage in particulate media Sattari, A. Shoarian; Toker, Nabi Kartal (Elsevier BV, 2016-04-01) Soil-water characteristic curve (SWCC) is widely used for obtaining mechanical and hydraulic properties of unsaturated soils, such as shear strength, deformation, permeability, and flow. An innovative approach, where a meso-scale medium is generated based on particle size distribution and void ratio of non-plastic soils, for estimating the drying SWCC is developed. With application of the finite difference and Newton-Raphson (Jacobian) approximations, the air-entry pressures of pore bodies in inter-particle...
Experimental and modelling study on nonlinear time-dependent behaviour of thin spray-on liner Güner, Doğukan; Öztürk, Hasan (Elsevier BV, 2019-02-01) Thin spray-on liners (TSLs) are fast-setting multi component polymeric materials applied on rock or coal surface with a thickness of 2-5 mm that have fairly high tensile strength, adhesion, and elongation capabilities. Compared to conventional surface support elements, TSLs with polymer content exhibit different material responses over time. As a matter of fact, the creep behaviour of TSLs under a constant load has a significance for the evaluation of the long term performances of TSLs. This paper investiga...
Residual Shear Strength Measured by Laboratory Tests and Mobilized in Landslides Mesri, Gholamreza; Huvaj Sarıhan, Nejan (American Society of Civil Engineers (ASCE), 2012-05-01) Drained residual shear strength measured by multiple reversal direct shear or ring shear tests has been successfully used for over four decades for stability analyses of reactivated landslides in stiff clays and clay shales; A body of literature has accumulated in recent decades, claiming that "healing" or "strength regain" is realized in time on preexisting slip surfaces already at residual condition. In other words, the shear stress required to reactivate a landslide is claimed to be larger than the drain...
Seismic energy dissipation in deteriorating systems through low-cycle fatigue Erberik, Murat Altuğ; Sucuoğlu, Haluk (Wiley, 2004-01-01) Energy dissipation characteristics of structural members which exhibit both strength and stiffness deterioration under imposed displacement reversals are investigated. In the experimental part, 17 reinforced concrete beam specimens were tested under constant and variable amplitude inelastic displacement cycles. The constant-amplitude tests were employed to determine the low-cycle fatigue behaviour of specimens where the imposed displacement amplitude was the major variable. A two-parameter fatigue model was...
