Model Test for Elongation Behavior of Geocell Structural Layer

Adopting the self-made stretching device and applying the test of material strain gauge, the stretching behavior of geocell structure is studied on the stretching characteristics and deformation pattem with two different fillings, including loess and grit.The research result displays that the breakage of geocell structure occurs at te fixed point £¨point of action£©, and the intensity of welding point is the main controlling factor. The intensity of geocell structure filled with grit is greater than the geocell structure with loess. The curve of stretching strain of geocell behaves obviously the following three phases, i.e. interfacial friction, geocell material stretched and breakage.
