| 摘 要： | 为研究路面热铺沥青对玻璃纤维土工格栅力学性能的影响，选取了3种规格的玻璃纤维土工格栅，对不同温度作用的玻璃纤维格栅试样，就温度对其拉伸断裂强力和断裂伸长率2项力学性能的影响进行了大量的试验研究：并运用统计学中的柯尔莫哥洛夫检验法和格拉布斯准则对试验结果进行了分析及异常值剔除，得到其温度与拉伸力学性能关系曲线；在此基础上，运用标准不确定B类评定办法对试验结果进行了评定。分析研究表明，经不同温度作用后，玻纤格栅断裂强力和断裂伸长率无明显变化；力学性能与温度之间未呈现出明显的统计规律性.

| Abstract: | To investigate the influence of hot-lay asphalt on mechanical property of glassgrid,three kinds of glassgrid set were selected and large numbers of experiments concerning temperature's influence on fracture strength and elongation rate were carried out at different temperatures.Experimental data were analysed and abnormal values were removed by using the Kolmogorov test and the Grubbs' Criterion respectively to obtain the temperature-tensile mechanical properties curves.On this basis,the experimental result... |
