| 摘要： | The frictional mechanism of geogrid-soil interaction is considered in two parts: one is passive resistance from the soil mass ahead of the transverse ribs and the other is produced by the frictional resistance. The factors influencing the mechanical performance of geogrid-soil interaction are studied. With three types of geogrids, three types of soils (two sandy soils and one clayey soil), and various testing conditions, a series of pullout tests for geogrid was conducted. Through the testing program, the significance of influencing factors and the strain contribution measured by strain gauges are studied. According to the results of the experiments, the pullout resistance of geogrid tends to increase as the confining pressure is increased. For sandy soils, the passive earth pressure offers the most pullout resistance; when using fine grained soil, it is replaced by friction resistance. |
