摘要
在常规土力学实验装置基础上通过适当升级改造,实现了路基压实土的流变实验目的,形成了较为完整的路基压实土的流变实验方案,获得可用于路基设计的流变力学参数,并通过理论分析和实验数据验证了方法的可行性.实践表明本方法成本低、可操作性强,实验结果能较好地应用于工程设计和施工.
Through appropriate upgraded reformation on the foundation of conventional soil mechanics experimental device,rheological experimental purposes of subgrade compacted soil was achieved.It formed a fairly complete rheological experimental scheme of subgrade compacted soil,obtained the rheological mechanics parameters used for subgrade design,and it verified the feasibility of this method by theoretical analysis and experimental data.The practice shows that this method is low cost,easy to operate,and the experimental results can be well used for engineering design and construction.
