| 摘 要： | 根据扁铲的受力机理分析了扁铲测试所获得的参数,对比了由扁形铲板和圆锥体贯入土体所产生的土体变形,事实表明扁铲探头对土体扰动较小,对水平应力具有较高的灵敏度,不仅可以用来测试土体强度,还可以反映土体的变形参数。通过与其它原位测试和土工试验成果进行对比,本文对南京地区粉砂的DMT测试成果进行了阐述。结果表明经地区经验修正公式计算所得出的DMT测试成果具有一定的适用性。

| Abstract: | The parameters acquired from the flat dilatometer test(DMT) are analyzed according to the mechanism of the dilatometer work,and the deformation of soil mass from the penetration of the wedge and the cone is compared.It is shown that the disturbance made by the probe of DMT is less than that by the cone,and DMT has a high sensitivity to horizontal stress,which can not only be used to test the strength of the soil but also to express the deformation parameters.Through the testing results of silty sand by using DMT in Nanjing,it is indicated the results calculated from the empirical formula have certain applicability. |
