Failure Mechanism in Geobag Structure
نویسنده
چکیده
This paper presents observed failure modes for a geobag structure from a series of physical modeltests. Six hundred bags were employed to observe the failure in terms of friction force, water depth, flow rateand bag aging. Three different failures are reported. An analysis of the effect of bag aging shows that 52% ofsaturated bags gain weight in the range 0 to 5% and about 70% of initially dry bags gain weight in the range10 to 20%. The outcome indicates the importance of bag aging in the ‘incipient failure’. These observationswill eventually be used to validate an existing numerical model. Key-Words: Geobag, failure modes, bag aging, failure mechanisms, Jamuna River.

Reducing Local Scouring at Bridge Piles Using Collars and Geobags
The present study examines the use of collars and geobags for reducing local scour around bridge piles. The efficiency of collars and geobags was studied experimentally. The data from the experiments were compared with data from earlier studies on the use of single piles with a collar and with a geobag. The results showed that using a combination of a steel collar and a geobag yields the most s...
متن کاملStudy on the Interactions between Mechanical and Structural Properties of the Thermobonded Nonwovens
Thermobonding is widely used in producing of nonwovens. In this study various layers of thermobonded nonwovens were produced by altering the pressure, binder fibres and quality of blending. Mechanical properties of the so-called layers such as breaking strength and breaking elongation, bending rigidity and air permeability were assessed consequently. The structure of the layers was then studied...
متن کاملA 3D Discrete Element Analysis of Failure Mechanism of Shallow Foundations in Rocks
In this research work, a 3D numerical modeling technique is proposed based on the 3D particle flow code in order to investigate the failure mechanism of rock foundations. Two series of footings with different geometries and areas are considered in this work. The failure mechanism obtained is similar to that of the Terzaghi’s but there is a negligible difference in between. Lastly, one equation ...
متن کاملFailure mechanism and soil deformation pattern of soil beneath interfering square footings
In this research, the variation of ultimate bearing capacity, failure mechanism and deformation pattern of soil beneath two closely square footings have been studied using numerical methods. It is assumed that the adjacent footings are constructed on the surface of sand. The presented numerical analyses are based on explicit-finite-difference code, FLAC3D. The elasto-plastic behavior of soil is...
متن کاملSiesmic Assessment og Ductility and Strength Capacities of Low-Rise R. C. Buildings
This paper presents a methodology for the assessment of ductility and strength capacities in low-rise buildings. This method utilizes the characteristics of force-displacement for the lowest story level or considers the weakest story in any given low-rise building for its primary analysis. Calculations are based on two levels of earthquake motions, namely strong earthquakes (PGA=0.3 g), and ver...
