摘要
围岩大变形防控是深部地下空间开发的核心技术难题。为掌握相关技术研发现状、探明研发热点和未来研发方向,推动我国围岩大变形防控技术体系的进一步完善,采用BERTopic主题建模算法对围岩大变形防控技术领域专利进行专利热点主题识别与演化趋势分析。主要获得以下结论:我国在该技术领域的专利申请集中在2010年以后,目前仍处于快速发展阶段;主要研究热点包括复合衬砌、让压钢架等支护结构,恒阻、升阻锚索与吸能构件,以及围岩计算模型、监测传感器等防控预警技术;未来基于多源数据的大变形机理研究,融合智能化、数字化技术的大变形预测方法,以及高性能工程材料研发将是主要的研究方向。
The large deformation of surrounding rock is a core technical problem during the development of deep underground space.In order to explore the research status,hotspots and future direction,and improve the large deformation control technology system efficiently,the BERTopic topic model was adopted to analyze hotspots and development trend of the patents about the large deformation control technology.Main conclusions is following:Chinese patent applying in this field is concentrated after 2010 and still keeps a rapid development at present.Main subjects include composite linings,yielding steel frames and other support structure,constant resistance anchor cables,increasing resistance anchor cables and energy-absorbing component,rock calculation model,monitoring sensors and other early warning technology.In addition,the mechanism research based on multi-source data,the prediction of large deformation integrating intelligent and digital technology,and advanced engineering materials will be main directions of patent development in the future.
