【 摘 要 】

Development of infrastructure planning especially bridges must consider the potential factors of disasters such as earthquakes and scouring. Some bridges in Indonesia have been damaged before they reach the age of the bridge. In general, existing bridges in Indonesia experienced many failures caused by scouring on the abutments and pillars of the bridge. This study aims to identify the types of damage to the substructure of the bridge due to the occurrence of scouring. Cipamingkis bridge at the location of West Java province road becomes the object of the case in this study. Cipamingkis bridge was built in 1986. The bridge is cracked and collapsed due to the collapse of the bridge foundation hit by the flood based on research that has been done by Institute of Water Resources Engineering in 2017 river condition until now still experiencing a decrease of a river bed. Besides due to the tendency of decreasing the bottom of the river, the problems that occur are also the activity of excavation C and scouring due to the bend of the river. The reinforcement system is determined by the value of the condition (rating factor). Some of the things that are recommended from some analysis and evaluation results are to build a new single span bridge with a length of 60 meters, retrofitting existing pillars, and making of abutment safety building using gabion. The pillar reinforcement and bridge replacement system is designed with a safety factor (SF) greater than 2 so that bridges are safe and capable of carrying service load.
