填方材料变形模量与压实度的关系

简便快捷、准确客观检测和监控填土压实度质量是工程施工与监理、工程建设与管理等追求的目标，变形模量作为一种路基强度指标，可以反映路基特性。采用落球式测试技术为手段，在相同碾压条件下，测试同类填方材料路基的变形模量与压实度，并对其进行函数拟合分析，研究填方材料的变形模量和压实度的内在关联，建立变形模量与压实度的关系模型，最后应用所得模型对填方工程质量进行监控、检测，并与传统的挖坑灌砂法对比验证，以明确变形模量与压实度的关系模型的可行性。

Relationship Between Deformation Modulus and Compaction Degree of Fill Materials

Engineering construction,supervision and management require a fast accurate way to detecte or monitor the degree of compaction of filling. As a strength indicator, deformation modulus can reflect the characteristics of subgrade. By the falling-ball technology, the deformation modulus and degree of compaction are tested in the case of the similar materal filled subgrade and analysed by function fitting. A relationship model of the deformation modulus and the degree of compaction, is found out. Also the model is applied to detecting or monitoring the quality of filling engineering by the researchers. By compa- ring the results of this new model and the sand trenching and filling method, the feasibility of this relationship mode can be confimed.
