| 摘 要： | 以弹性理论中的Mindlin解为基础导出了一般饱和黏性土的扁铲侧胀试验与应力铲试验成果间的关系式,并得出应力铲试验中的初始水平总应力σh0大于扁铲侧胀试验中膜片向土中膨胀之前作用在膜片上的接触压力p0。用湖州地区铁路工程的实际资料进行对比分析,结果令人满意。

| Abstract: | The relationship between the results of horizontal stresses measured from The Flat Dilatometer Test(DMT) and The Total Pressure Cell Test(TPCT) in the saturated clay was developed based on the Mindlin’s elastic solution.It is concluded that the initial total stress σ h0is greater than the contact pressure p0 on the DMT membrane before the inflation.This result was verified by the test results using DMT and TPCT in a railway project in Huzhou area. |
