The invention relates to a civil engineering specification field knowledge graph construction method and system, and the method comprises the steps: screening out statements which need to be extracted in a specification text, carrying out the modification, selecting sentences which accord with the definition of a Schema label, and enabling the sentences to be suitable for the extraction of a neural network model; carrying out model training on the screened part of texts, and carrying out data labeling on a training set according to a designed triple Schema label to obtain a triple training set in the field of civil standard texts; a CE-CasRel model is constructed, the marked data set is used for training, and the verification set is used for verification; inputting the obtained standard text to be extracted into the trained CE-CasRel model, extracting a triple in the civil engineering standard field, and storing the triple in a json file; reading a json file, analyzing triple data, and establishing a civil sp
