Recently, safety inspection of retaining wall structure is recognized as very important problem because many collapses have occurred in excavation and earth plate construction process by the uncertainty factors of climate and ground environment as well as increase of excavation depth due to enlargement trend of excavation construction. However, similar retaining collapse accidents occur repeatedly due to the lack of analysis of the relationship between collapse occurrence factors(collapse cause, risk factor, etc) as well as the analysis of collapse conditions for each construction step of soldier pile retaining. From this viewpoint, the object of this study is to propose the methodology of retaining collapse prevention to contemplate rational measures of excavation safety management targeting 21 accidents in soldier pile retaining work from 1993 to 2021. In order to achieve the object of this study, risk factors for the collapse of retaining wall were derived for each survey target, and the influence on the ground by risk factors of collapse was considered through case study. The collapse causes was grouped for each retaining installation step, and retaining collapse process was analyzed for each collapse causes. Based on the case study and excavation work guide, we suggest the classification viewpoint of safety management items and composition system of checklist as the countermeasure for preventing collapse accidents in retaining wall construction.
