基于知识图谱的盾构施工辅助决策系统设计和开发

Design and Development of the Shield Construction Assistant Decision-making System Based on the Knowledge Graph

利用盾构法施工相关文献与案例专报,设计基于知识图谱的盾构施工辅助决策系统,指导工程技术人员进行盾构施工决策。在建立盾构施工标准词库的基础上,提出盾构施工知识图谱本体架构;采用BiLSTM与规则结合的中文分词模型法对来源于论文和专报中的工程案例知识进行半自动抽取,构建可拓展的盾构法施工知识图谱。在此基础上,基于知识图谱节点权重的子图相似度特征,设计并开发盾构施工决策推荐算法,为盾构法隧道施工遇到的实际问题提供解决措施和参考方案,保障施工顺利进行。

The literatures and case reports of shield construction are utilized to design a shield construction assistant decision-making system based on the knowledge graph for the purpose of guiding engineering and technical personnel to make shield construction decisions. On the basis that a standard lexicon of shield construction is created, the knowledge graph ontology architecture of shield construction is proposed. The Chinese word segmentation model method combining Bi LSTM and rules is employed to semi-automatically extract engineering case knowledge derived from papers and special reports and construct the extensible shield construction knowledge graphs. On this basis, a recommended algorithm for shield construction decision making is designed and developed according to the subgraph similarity characteristics of knowledge graph node weights to offer solutions and reference schemes for actual problems encountered during shield tunnel construction and ensure successful construction.
