...M. Pinho-Lopes; A. M. Paula; M. L. Lopes This paper contributes to understanding how installation damage of geosynthetics influences their long-term response and design. A geotextile and a geogrid were exhumed after installation under real conditions; their long-term tensile behaviour...

...M. Pinho-Lopes; A. M. Paula; M. L. Lopes This paper contributes to a better understanding of how installation damage of geosynthetics can affect soil–geosynthetic interaction during pullout and inclined-plane shear. The effects of installation damage induced in field trials of a woven geotextile...

... understanding whether this is representative of the pullout response of geogrids when confined in soil. The effects of installation damage induced in field trials of two extruded geogrids and one composite with a grid structure were studied. Pullout tests were used to characterise the impact of installation...

...S.Y. Lim; J.S. McCartney ABSTRACT: The reduction factors used to account for the impact of installation damage on the tensile strength of geogrids employed in mechanically stabilised earth (MSE) walls and reinforced embankments are usually obtained from field tests that simulate actual construction...

...C.-C. Huang; Z.-H. Wang ABSTRACT A series of laboratory tests was performed to simulate installation damage of two flexible geogrids. These test results are analysed in conjunction with the results of some large-scale field tests and laboratory tests reported in the literature to determine...

...C.-C. Huang A series of laboratory cyclic loading tests was performed to investigate the effects of load intensity and particle size of aggregates on installation damage of a flexible geogrid. Stress–strain characteristics of the damaged flexible geogrid are also compared with those obtained from...

...Huang Ching-Chuan; Chiou Shuay-Luen A series of laboratory tests simulating installation damage was carried out on four types of woven geogrid. Relationships between index properties of the geogrids and the loss in ultimate tensile strength, strain at failure and tensile stiffness of the geogrids...

Bathurst CONVERSION OF GEOSYNTHETIC STRAIN TO LOAD USING REINFORCEMENT STIFFNESS ABSTRACT: Measurements indicative of the internal behavior of full-scale geosynthetic...

.... From simple tensile testing, the reduction factor for installation damage, RF_ID, was measured to be 1.42. Stepped isothermal method tests on the undamaged geosynthetic gave a creep-rupture characteristic with RF_CR = 1.70 for 106 hours (114 years). Thus...

...P.J. Fox; E.J. Triplett; R.H. Kim; J.T. Olsta Field tests were conducted to assess installation damage for an adhesive-bonded, and a needle-punched, geosynthetic clay liner (GCL). GCL panels were laid on a prepared subgrade and covered to varying thicknesses with clean angular sand and clean...

...T.M. Allen; R.J. Bathurst The current practice to determine the combined geosynthetic strength reduction due to installation damage and creep is to multiply the individual strength reduction factors for damage and creep together. However, it is difficult to know if this procedure results...

...T.M. Allen; R.J. Bathurst Installation damage can be expected to modify the mechanical properties of geosynthetics in reinforcement applications. The paper reviews data from controlled installation damage trials reported in the literature and other sources. Geosynthetic properties taken from...
