A damage-softening model for a reinforced soil interface is proposed based on the trilinear of pullout interface, aiming at softening phenomenon geogrid during process and considering damage process. The variable factor D introduced, it assumed that function displacement. two-parameter Weibull distribution used to express evolution law interface. Based basic control equation calculation stress ...

In order to obtain the optimal spacing of closely spaced footings under cyclic dynamic loading, model tests were carried out on unreinforced and reinforced sand foundations. The influence center point (S) bearing capacity foundation load is discussed. test results show following: (1) peak largest when S/B = 2.0 (B width footing), ultimate 20% higher than that foundation. (2) vertical soil press...

The strength and deformation properties of maritime geotechnical structures made primarily calcareous sand are critical for project safety. geogrid reinforcement is developed as a promising approach to improve the mechanical sand. This study investigates property biomodified via microbially induced calcite precipitation (MICP) process effectiveness A series unconsolidated undrained triaxial exp...

The aim of this study was to improve the characteristics natural collapsible soils using geogrid-encased stone column technique. For purpose, 20 large-scale specimens columns were prepared rigid metal cylinders with a diameter 308 mm and height 97 154 according unit cell theory. aspect ratio 10% 25%. occurrence bulging failure, considered six times diameter. encased geogrids varying stiffness f...

Geosynthetic materials have been demonstrated to be an accurate element in civil engineering, specifically the field of pavement. Regarding implementation these asphalt mixture layers, geosynthetics, such as geotextile and geogrid, used delay crack propagation and/or increase fatigue life. However, use material is based on experience learned or results obtained from testing a reduced scale labo...

When constructing flood protection structures such as river levees, oftentimes due to various factors engineers must design composite structures, i.e., reinforced earthen which comply with all the stability criteria. The most common way of reinforcing is usage geosynthetics, or mostly geogrids when talking about stability. Since geosynthetics are man-made materials produced in a controlled envi...
