“…Zhang et al and Hou et al [ 30 , 31 , 32 ] proposed H–V strips with no open grid and found that H–V strips perform better than conventional planer ones. Hou et al [ 33 ] indicated that vertical stripes provide passive resistance against soil, significantly increasing the shear strength of the soil. Zhang et al [ 34 ] studied the influence of H–V strips on the bearing capacity of the foundation through a series of model tests.…”

A series of model tests were conducted to investigate the bearing capacity and reinforced mechanism of a horizontal–vertical (H–V) geogrid-reinforced foundation. The bearing capacities of the unreinforced foundation, the conventional geogrid, and the H–V geogrid-reinforced foundation were compared. The parameters, including the length of the H–V geogrid, the vertical geogrid height, the depth of the top layer, and the number of H–V geogrid layers, are discussed. Through experiments, it was found that the optimal length of H–V geogrid is around 4B, the optimal vertical geogrid height is approximately 0.6B, and the optimal depth of the top H–V geogrid layer is between 0.33B and 1B. The optimal number of H–V geogrid layers is 2. The result also indicates that the bearing capacity of H–V geogrid is almost 1.7 times greater than that of conventional geogrid. Additionally, the maximum top subsidence of H–V geogrid-reinforced foundation decreased by 13.63% compared to that of conventional geogrid-reinforced foundation. Under the same settlement, the bearing capacity ratio of two H–V geogrid-reinforced foundation layers is 75.28% higher than that of one layer. The results also demonstrate that the vertical elements of H–V geogrid interlock the sand from being displaced under the applied load and redistribute the surcharge over a wider area, thereby increasing the shear strength and improving the bearing capacity of an H–V geogrid-reinforced foundation.

As a kind of supporting material applied to the supporting structure, steel-plastic geogrid mainly goes through the tensile strength to bear the load from the rock mass. Tensile strength is an important indicator of the steel-plastic geogrid mechanical properties. Tensile strength directly affects the security and stability of the steel geogrid in support of the project. Through the test of indoor geogrid stretching which combines different sizes' geogrids with different elongation rates, tensile strengths of these geogrids were compared. The findings are as follows: (1) The stretching rate has a significant effect on the tensile property of steel-plastic geogrid. When the strain is constant, the higher the stretching rate is, the lower the tensile strength of the geogrid will be. When the stretching rate is constant, the greater the strain plastic geogrid is, the greater the tensile strength will be; (2) The peak degree always decreases with the extension rates' increase; a higher tensile strength material means a smaller reducing amplitude; under the conditions of the same stretch rate, the lower the tensile strength of the geogrid is, the higher the peak strain will be; (3)The influences on different geogrids vary when the tensile rates are different. Steel-plastic geogrid get less influenced by the stretching rate than the plastic geogrid.

Abstract:Tensile strength is an important indicator of the steel-plastic geogrid mechanical properties. Tensile strength directly affects the size of the steel geogrid security and stability in support of the project. Stretching through the indoor geogrid test for combinations of different sizes and different geogrid elongation rate, tensile strength of the geogrid were compared. The findings are as follows: (1)The size of the stretching rate has a significant effect on the tensile properties of steel-plastic geogrid. The strain is constant, the stretching rate, the lower the tensile strength of the geogrid; stretching rate is constant, the greater the strain Plastic geogrid, the greater the tensile strength;(2) Peak strain increases with extension rates decrease; higher tensile strength material to reduce the amplitude of the smaller; under the same conditions of stretch rate, the lower the tensile strength of the geogrid, the higher the peak strain;(3)Different effects under different specifications geogrid tensile rate, steel-plastic geogrid degree of influence by the stretching rate is less than the plastic geogrid.
