玻璃纤维因为它的高力量，好坚韧，和抵抗，增强的塑料 geogrid 在土壤加强的地里有宽应用到环境应力，爬抵抗和强壮的稳定性。为了得到马力大的玻璃，纤维增强了塑料 geogrid，它的机械特征，性质和 geogrid 的物理机械索引被做完它的原料，生产过程和重要优秀索引的学习。分析和学习与装载速度被成为了机械性质到 geogrids，三轴的压缩，温度张力的测试和 FLAC ^3D 数字模拟，因此在裂缝获得它的排水量时间曲线，碎力量和延伸的机械参数。一些结论能如下被得出：用玻璃纤维材料， knurling 和涂的设计过程，破裂力量和 geogrid 的腐蚀抵抗的(a) 极大地被改进，土壤的联锁的咬能力被提高。geogrid 的破裂力量与温度和装载的率有关的(b) 。当包围岩石压力被修理时，力量和增强的土壤的反变丑能力显著地与增加增强的层被提高。撤退测试显示出的(c) 在 geogrid 之间的积极关联排水量和行动时间。是的(d) 新增强的材料，玻璃纤维增强了塑料 geogrid 不在理论研究和实际经验是足够成熟的，它因此在理论学习和实际革新两个都成为了一个迫切问题。

英文摘要：

Glass fiber reinforced plastics geogrid has a wide application in the field of soil reinforcement because of its high strength, good toughness, and resistance to environmental stress, creep resistance and strong stability. In order to get high-powered glass fiber reinforced plastics geogrid and its mechanical characteristics, the properties and physical mechanical index of geogrid have been got through the study of its raw material, production process and important quality index. The analysis and study have been made to the geogrid＇s mechanical properties with loading speed, three-axial compression, temperature tensile test and FLAC3D numerical simulation, thus obtain the mechanical parameters of its displacement time curve, breaking strength and elongation at break. Some conclusions can be drawn as follows： （a） Using glass fiber materials, knurling and coated projection process, the f~acture strength and corrosion resistance of geogrid are greatly improved and the interlocking bite capability of soil is enhanced. （b） The fracture strength of geogrid is related to temperature and loading rate. When the surrounding rock pressure is fixed, the strength and anti-deformation ability of reinforced soil are significantly enhanced with increasing reinforced layers. （c） The pullout test shows the positive correlation between geogrid displacement and action time. （d） As a new reinforced material, the glass fiber reinforced plastics geogrid is not mature enough in theoretical research and practical experience, so it has become an urgent problem both in theoretical study and practical innovation.
