基于文献计量学的近20年国内非饱和土研究综合分析

Bibliometrics-based Comprehensive Analysis of the Past 20-Years’ Researches on Unsaturated Soil

工程实际中接触的土大都处于非饱和状态,非饱和土研究影响广泛。以中国知网数据库作为数据源,对1998年~2018年近20年间国内发表的非饱和土文献进行搜集。基于文献计量学相关理论和方法,对搜集的论文集分别从产出时间、期刊分布、高被引作者、合作研究、主题聚类等层次进行全面梳理。结果表明,非饱和土领域研究的核心人物、机构已经形成且之间交流较为密切,他们为非饱和土研究奠定了良好的基础;非饱和土领域研究成果总体质量较高,聚焦在"土水特征曲线研究"、"强度特性研究"、"本构模型研究"及"工程应用研究"等四个方面。非饱和土领域研究处在体系完善阶段,其发展应注重理论研究与工程应用的结合。

The soils encountered in projects are mostly unsaturated. Therefore, the study of unsaturated soil is of wide influence. In this paper, 20-years’(1998 to 2018) domestic literatures are collected from the CNKI database. On the basis of relevant bibliometrics theories and methods, the collected literatures are analyzed from the aspects of output time, journal distribution, highly cited author, cooperative research and topic clustering. The results show that:(a) The core researchers and institutions have established themselves, and had close communication and laid a good foundation for the study of unsaturated soil;(b) They made good achievement on unsaturated soil by focusing on four main aspects of soil-water characteristic curve, strength characteristic, constitutive model and engineering application. The study of unsaturated soil is now in a system perfection stage, and its development should emphasize the combination of theoretical research and engineering application.
