Abstract: With the increasing demands for the railway passenger and cargo capacities, To expand of the existing single railway line to double lines is one of the important ways. With the constraints of station locations, and topographic conditions, the railway embankments might be constructed near the reservoir banks. As a result, the reservoir protection projects emerged.  The protection mitigation selection related to many factors, such as, the safety operation of the existing rail line, the safe and stability of the new rail line and reservoir banks, finally, the environmental concerns. The viable measures include riprap protection, piled foundation and cofferdam to isolate the embankments. These measures should also consider the geotechnical conditions and abovementioned factors.
