摘要
利用新近研制的大型现场室内两用直剪仪,对两种不同性质的砂样进行了剪切试验。在对干砂的直接剪切试验特性进行综述的基础上,从多方面对该大型直剪仪得出的干砂剪切试验数据进行了分析验证,结果表明该大型直剪仪得出的试验数据一致性好、可靠性较高,说明该大型直剪仪的基本剪切性能稳定,可进一步应用于相关岩土材料的试验研究。
Direct shear tests on two different kinds of sand were conducted by the newly developed large direct shear apparatus designed for field and laboratory test. On basis of the illustration on direct shear characteristics of sands, the test data of sands from the large direct shear tests are analyzed in different views. The analytical results show that the test data from the large direct shear apparatus are consistent with high reliability; and it is shown that the basic shear capability of the large direct shear apparatus is better. The large direct shear apparatus can be applied to other corresponding geo-material investigations.
