玻塑复合土工格栅强度高,冲击韧性好,耐环境应力、抗蠕变性能强,且在正常使用状态下能够保持长期稳定的性能。通过对玻塑复合土工格栅的原料、工艺流程、性能指标的介绍,并通过现场拉伸试验,对不同温度下格栅的纵向、横向断裂强度以及断裂伸长率进行了分析研究,得到如下研究结论:(1)格栅条带采用纤维材料,能够抵抗侵蚀和气候变化,保证其性能的稳定性;(2)格栅的断裂强度与温度呈正相关,断裂伸长率与温度呈负相关,并经过一定时间后趋于稳定;(3)结构采用特殊工艺,提高了格栅的抗剥离撕裂强度和对土体的嵌锁咬合能力,玻塑复合土工格栅的开发在我国正处于起步阶段,作为加筋、加固材料必将在土木工程领域有着广阔应用前景。
Glass-plastic composite geogrid high strength, impact toughness, resistance to environmental stress, creep resistance, and under normal conditions to maintain long-term stability of the performance. Through the introduction of raw materials, process flow and performance index of glass-plastic composite geogrid, and through the field tensile test, the longitudinal and transverse rupture strength and elongation at break of the grid under different temperatures were analyzed and studied as follows The conclusions are as follows: (1) The grid strips are made of fiber material, which can resist the erosion and climate change and ensure its stability. (2) The rupture strength of the grid is positively correlated with the temperature, and the elongation at break is negatively correlated with the temperature , And tends to be stable after a certain period of time; (3) The structure adopts a special process to improve the anti-peel tear strength of the grille and the interlocking and occluding ability of the soil. The development of the plastic-plastic composite geogrid is in our country The initial stage, as reinforced, reinforced materials will certainly have broad application prospects in the field of civil engineering.
