填石路堤研究进展与展望

通过填石路堤压实与检测、稳定性分析、沉降预测三方面回顾,指出级配不能准确地反映填石材料的结构特征、不同压实检测方法相关性差、压实质量评定标准模糊、稳定分析和沉降预测参数获取方法和考虑因素简单是目前填石路堤研究中存在的主要问题.准确描述填石材料的结构特征、对各种施工工艺组合下的压实质量的检测方法的相关性进行研究,并提出定量的统一的评定标准,以及应用可靠的方法获取稳定分析和沉降预测所需要的参数,建立多场耦合作用下稳定性分析和沉降预测模型,并对各种模型的适应性进行检验是填石路堤进一步的研究方向.

The Progress and Prospect of Embarkment Rock-filled Study

After the study of embankment rock-filled from the compaction and inspection methods,stability analysis and settlement prediction equation is reviewed,the paper points out that the structure characteristics can not be described by graduation,correlativity is not good between different inspection methods,evaluation standard is fuzzy,and the methods to acquire parameters are imperfect and factors considered are simple for stability analysis and settlement prediction which are the main problems existing in embankment rock-filled study.And it describes the structure characteristics accurately,studies the correlativity between different inspection methods under various compacting technical assembles,raises quantitative consistent evaluating standards and applies reliable methods to acquire parameters and establishes different field coupling models for stability analysis and settlement prediction,and the verification of the models are further studied in embankment rock-filled.
