چکیده

This study proposed a numerical procedure to simulate the deformation behaviors of the uniaxial compression test of single gabion and of the lateral loading test of full scale gabion retaining wall. The validity of the numerical procedures is verified by the comparison of the measurements with the simulations of deformation behavior. In addition, two evaluation equations which are capable of estimating the horizontal and the vertical displacement of the front face of laterally loaded gabion structure are presented for engineering practice. The numerical results indicates the deformation mode of a loaded gabion structure can be effectively captured in numerical model when incorporating a structural beam element with limit axial stiffness and relatively low or zero flexural stiffness. It is also found that the apparent total shear modulus of gabion structure, which has taken the compound shear deformation behavior of wire mesh and infilled stone into account, should be adopted in numerical modeling instead of using the shear modulus of infilled stone itself.

Experimental Study of the Effect of Gabion Structure on the Energy Dissipation of Submerged Hydraulic Jump Downstream of Ogee Spillway

In the last decade, the use of gabion structures in hydraulic engineering for stabilizing the structure due to its high density and weight has become widespread. Also, the material's roughness and porosity cause it to be used in energy dissipation and drainage projects. This study evaluates the relative energy dissipation of gabion structures downstream of the ogee spillway in the conditions of...

Seismic Behavior of One-Storey Gabion-Box Walls Buildings

Gabion-boxes, made with steel wire mesh and filled with stones of appropriated size, are normally stacked up one into another to form a retaining wall. Given their reduced costs and the easy availability of their constituting materials, gabion-box walls have been extensively used in developing countries (such as Nepal) also to realize simple one-storey residential buildings. In recent years, ma...

Sedimentation efficiency of small dams in channels (Case study: Kermanshah province)

Small sediment dams are the key structures for controlling sediment flow and improving the course of waterways in watersheds. In Kermanshah province, the efficiency of these structures in sediment accumulation has been less studied and evaluated. This study aimed to investigate the efficiency of these structures in sediment retention and flood control in three watersheds of the province. For th...
