本文从控制铁路路基施工质量的角度出发,针对动态平板载荷仪和轻型动力触探的特点,通过现场检测得到的数据,分析了动态变形模量Evd和轻型动力触探锤击数N之间的相关关系。结果表明,动态变形模量Evd和轻型动力触探锤击数N之间具有很好的线性回归关系,根据这一关系,进一步研究了轻型动力触探检测多层路基压实度的可行性,最后初步探讨了路基压实质量检查的时效问题。
In this paper, from the point of view of controlling the construction quality of railway subgrade, according to the characteristics of dynamic plate load meter and light dynamic probe, the dynamic deformation modulus Evd and light dynamic probe hammering number N relationship. The results show that there is a good linear regression relationship between the dynamic deformation modulus Evd and the number N of light dynamic probe, according to this relationship, the feasibility of light dynamic penetration testing of multi-layer roadbed compaction is further studied, Finally, the paper discusses the aging problem of subgrade compaction quality inspection.
