Chinese grammar is a formal rule describing the grammatical structure of Chinese language, and it is also an important cornerstone of Chinese language related research. In this paper, we take the Chinese relational clauses as the research object, and analyze the basic concepts of fuzzy context-independent grammar in Chinese relational clauses. Based on the characteristics of Chinese grammatical structure, the stack-maximum matching automatic word segmentation model is designed as the automatic word segmentation technique for the grammatical analysis model of Chinese relational clauses by combining the maximum matching method and the stacking technique. For the analysis of grammatical knowledge points in Chinese relational clauses, they are analyzed in modules by decomposing them into lexical and syntactic parts. At the same time, the Chart algorithm is introduced as the grammatical analysis algorithm for Chinese relational clauses, and a grammatical analysis model for Chinese relational clauses is constructed. The model is used to analyze the distribution of accusative constructions in subject relative clauses and object relative clauses, in which there is a significant tendency for accusative prepositional constructions in subject relative clauses (p0.05).
