Abstract

Abstract The dynamic penetration test was used to investigate the angle of shear strength of Danube gravel. The correlations for its determination are available in the standards and literature. From the data set of the results, the characteristic value of the angles of shear strength was derived according to the recommended statistical procedure from the second generation of Eurocode 7. The characteristic values of the angle of shear strength were evaluated for well-graded gravels, poor-graded gravels, and gravels with fine-grained particles of the Danube. The correlations, which were based on field tests and considered the genesis of the soil, were compared with laboratory test results and a table of the values from the Slovak standard, which are used for purposes of comparison. In our research we compared the characteristic field values of the angle of shear strength obtained in the laboratory to observe the effect of their genesis on the appropriateness of the correlations used. We conclude with recommendations for the regional correlations and suggest values of the angle of shear strength for the classes of gravels tested.

动态渗透试验得出的多瑙河砾石抗剪角度

摘要采用动态渗透试验来研究多瑙河砾石的剪切强度角。在标准和文献中都有测定该值的相关数据。根据结果数据集，按照第二代 Eurocode 7 推荐的统计程序，得出了剪切强度角的特征值。对多瑙河上等级较好的砾石、等级较差的砾石和颗粒较细的砾石的剪切强度角特征值进行了评估。根据现场试验得出的相关结果考虑到了土壤的成因，并与实验室试验结果和斯洛伐克标准中的数值表进行了比较。在我们的研究中，我们对实验室获得的剪切强度角的现场特征值进行了比较，以观察其成因对所用相关性的适当性的影响。最后，我们对区域相关性提出了建议，并对所测试的砾石类别的剪切强度角值提出了建议。
