| 摘 要： | 使用三种土工带，在中型直剪仪中进行拉拔试验，研究其应力应变关系，确定强度参数c*、ψ*，似摩擦系数f*和残余似摩擦系数F*。试验结果表明摩阻力f随正应力σv增加而增加，但并不是无限止的线形增加。指出某些土工合成材料制作工艺方面的不足，并对加筋土工程填料的选择提出建议。

| Abstract: | Systematic pull-out tests in middle direct-shear apparatus were carried out for the soil reinforced by three types of geobelfs.Based on the test results,stress-strain relationship is studied, and intensity indexes, pseudo-friction coefficient and residual pseudo-friction coefficient of the reinforced soil are determined.Disadvantages of some kinds of geosynthetics in workmanship are mentioned. Some conclusions and opinions which can accumulate data for engineering and design are also presented. |
