| 摘 要： | 以两组(各10块)某一规格的土工布为研究对象,按相应规范要求,采用自制夹具,在MTS810试验机(非专用试验机)上完成试验。针对两组试验数据进行分布检验,对异常数据进行判断并对其拉伸强度进行了不确定度评定。结果表明,用MTS试验机对土工布进行拉伸强度试验是可行的,测量的重复性是引入不确定度的最主要影响因素。

| Abstract: | The tensile strength test of two teams of geotextiles(each 10) are made with self-made clamp which meets the slanderer requirement on MTS 810(nonspecial-purpose test machine).Examining how the data which get from experiment distribute and determining abnormal data,then calculation of tensile strength and evaluation on measurement are finished with valid data.The result shows tensile strength test of geotextile can finish on MTS and measurement repeatability is to introduce the most important factors of unce... |
