The analysis of failure mechanism and crack propagation patterns of borehole grout stopper ring structure induced by non-uniform geostress in nearshore areas

Key Points

• Crack propagation patterns reveal significant vulnerabilities in borehole grout structures under non-uniform geostress.
• The analysis identified multiple failure mechanisms affecting structural integrity in nearshore areas.
• Utilizing stress analysis techniques, the study assessed how varying geostress impacts borehole grouting efficacy.
• Findings underscore the need for improved design considerations for borehole structures in regions with complex geostress.
