PE-HD植被网与单层土工网的拉伸性能

Tensile Performance of PE-HD Vegetation Net and Single-layer Geonet

高密度聚乙烯(PE–HD)植被网与单层土工网具有良好的边坡防护使用性能。采用拉伸试验装置对PE–HD纤维植被网与土工网进行了一系列的拉伸试验。通过试验研究在等速率下材料的伸长率与荷载之间的相互关系,得到了材料的纵向伸长率、横向伸长率、荷载变化规律,确定了不同伸长率的平均拉伸力、断裂平均用时等参数。试验结果表明,单层土工网的纵向、横向断裂拉伸力平均值小于植被网,单层土工网的断裂平均用时小于植被网。相关的试验结果可以为植被网与单层土工网的应用提供参考。

The high density polyethylene(PE–HD)vegetation net and single-layer geonet have good slope protection perfor-mance.A series of tensile tests were carried out on the PE–HD fiber vegetation net and geonet using the tensile test device.Through experimental research on the relationship between the elongation and load of the material at a constant rate,the longitudinal elonga-tion at break,transverse elongation at break,and load change law of the material are obtained,and the average tensile force,Param-eters such as the average time to fracture.The test results show that the average vertical and horizontal breaking tensile force of the single-layer net is less than that of the vegetation net,and the average time for the breaking of the single-layer net is less than that of the vegetation net.
