The invention discloses a comprehensive interpretation method for a geological structure surface form based on multiple outcrops. The method consists of five parts of establishment of a database, grouping of dominances, comparison of spatial relations, comparison of geological attributes and output of a result. The method comprises the steps of making an inquiry statistic in original exploration data according to basic engineering conditions and geological conditions to obtain a structure surface outcrop sample of a target rock mass part, and further obtaining dominance structure surface groups according to an outcrop occurrence by use of a polar iso-density map technology; performing spatial association searching on the specified structure surface outcrop sample according to an input occurrence deviation constraint parameter in the specified dominance group to obtain the rest of outcrop samples having position and occurrence association conditions with the specified structure surfaceoutcrop sample; and further screening and removing the outcrop samples according to structure surface properties to obtain all target samples with identical spatial positions, occurrences and geological attributes. Therefore, analysis and interpretation for a spatial form of a certain deterministic growth structure surface are implemented.
