土工薄膜指标刺穿强度试验 ,一般作为控制其生产质量的组成部分 ,也是独立的第三方对质量的保证。指标刺穿强度与土工薄膜的厚度和强度有关。过去一直采用两种试验方法来测试土工薄膜指标刺穿强度的特性。但是 ,这两种方法给出不同的结果。简略叙述这两种不同的方法 ,并就差别的产生进行讨论。 Geotextile index piercing strength test, generally as part of controlling the quality of its production, but also independent third-party guarantee of quality. Index piercing strength and the thickness of geotextile film and strength. In the past, two test methods have been used to test the puncture strength characteristics of geotextiles. However, these two methods give different results. Briefly describe these two different approaches and discuss the differences.
