Development of Flexible Structural Precast Concrete Conduits for Earth Dams

Conventional precast concrete conduits for earth dams are fixed with prestressed concrete (PC) steel or bolts at the joints. This leads to problems of ground-following performance and water leakage, which severely hinders the performance of these installations and the wider infrastructure of which they form a part. In this study, a new type of precast concrete conduit without PC steel or bolts is developed. The following three issues are...
