As a three-dimensional system with length, width and depth, the foundation pit is bound to have a pit angle effect. At present, the study of the foundation pit angle effect focuses on the influence of the “deep” of the foundation pit, while ignoring the analysis of the “wide”. In this paper, the relationship between the length of the adjacent edge of the foundation pit and the foundation pit angle effect is analyzed by using the flac3d finite difference software. It is found that the ratio of the adjacent length to the depth does not change the functional relationship between the influence coefficient of the foundation pit angle effect and the ratio of the foundation pit angle distance to the foundation pit edge length. When the ratio of the length of the adjacent side to the depth of the foundation pit is less than or equal to 7, the influence coefficient of the foundation pit angle effect increases linearly with the ratio of the length of the adjacent side to the depth of the foundation pit. When the ratio of the length of the adjacent side to the depth of the foundation pit is more than 7, the influence coefficient of the foundation pit angle effect is a fixed constant. Finally, the rationality of the research results is verified by engineering examples.
