充分利用轻便动力触探试验简便、灵活,快速的优点,通过大量的现场试验,针对一般粘性土地区低路堤地基土对轻型动力触探试验指标N10和基床土承载力σ以及N10和静力触探试验结果(综合比贯入阻力Ps)的数值关系的研究,建立了N10和σ以及N10和Ps的相关关系公式,最终确定了利用轻型动力触探试验检验低路堤地基土承载力的标准,确定了相应的土力学指标,为今后在低路堤地基土的勘察中,节约工程成本、缩短勘察周期以及减少工程设计的盲目性,提供了良好的参考依据。
In order to make full use of the advantages of simple, flexible and rapid testing of light dynamic penetration test, a large number of field tests are conducted to test the light dynamic penetration test index N10 and subgrade soil bearing capacity σ and N10 and static force The relationship between N10 and σ, N10 and Ps was established based on the study of the numerical results of the penetrating test results (integrated penetration resistance Ps). Finally, the criterion for testing the bearing capacity of subgrade soil with light dynamic penetration test was finally established , The corresponding soil mechanics index is determined, which provides a good reference for the future investigation of the foundation soil in low embankment, saving the project cost, shortening the survey period and reducing the blindness of engineering design.
