Introduction Geocells are geotextile-related products composed of single strips interconnected in several possible ways (extrusion, thermal bonding, gluing, hot melt, stitching, etc) to form a panel of adj
19、acent cells, where generally the contact between two elements occurs along lines or in specific points, and not uniformly on the whole surface. These lines or points are referred to as “junctions“. A geocell junction may fail in four different ways: 1) by shear (see Figure 1): when failure is caused
20、 by a force parallel to the junction itself; 2) by peeling or delamination (see Figure 2): when failure is caused by a force, normal to the junction, which separates the cells from each other at one edge of the junction; 3) by tensile stress (see Figure 3): when a force, normal to the junction, pull
21、s away the two cells adjacent to the junction; 4) by local overstressing (see e.g. Figure 4: geocells secured with pins) : when the fixation element locally overstresses the junction, leading to a compression, shear or peel failure. NOTE This can be considered as a performance property, in the same
22、way as a tensile test on seams/joints. It is therefore impossible to define one single testing method for measuring the junction strength of geocells. Hence this standard includes the principles for testing the four failure mechanisms explained above. These principles should be adapted to each singl
23、e product. In order to avoid confusion about the interpretation of figures, reference should be made to the exact test method in test reports and data sheets, e.g. EN ISO 13426-1, method A shear strength of internal structural junctions. 1 Scope This standard describes index test methods for the det
