On the expressway, culvert structures serve as a channel or channel connecting villages and towns blocked by clay. The culvert structures are mainly constructed of reinforced concrete or corrugated steel sheets in various ground conditions. Most culverts are divided into aging and damage trends according to the number of public years. However, most of the damage to the culvert structures applied on the soft ground is likely to be caused by the subsidence of the ground. In addition, even if the settlement of the paper sheet is stabilized, if the road is constructed at the upper part, the culvert structure is also expanded at the time of the expansion work, and damage due to a behavior different from that before the expansion work may be found. Therefore, in this study, the behavior of the culvert structures according to the ground supporting force was analyzed. For this purpose, the causes of damage are derived through design review and field investigation.
