it was shown that cohesion of strip geomembrane was increased, internal frictional angle was reduced, while both of lump geomembrane were increased considerately.
试验结果表明,条状土工膜提高的是黏聚力,其内摩擦角有所下降,而块状土工膜黏聚力和内摩擦角都有很大程度的提高;
the soil esp influence on soil internal frictional angle is small.
但土壤堿度对土壤内摩擦角的影响较小。
in this paper the joint profile expression and fractal theory are reviewed, and the fractal theory is used to study the frictional angle of the rock joint.
本文首先简要介绍节理形貌的描述方法和分形几何理论,然后将分形理论引人巖体节理摩擦角的研究中,得出了用分形维数表示摩擦角的经验公式。
