- Abstract
Overhanging pavement slabs on the defected subgrade are mainly caused by flood erosion that partially hollows out the subgrade, which leaves the highway in an unstable condition. This paper develops a kind of emergency repair technology of suspended road slab anchor pulling technology for this type of disaster, combining the working principle of self-anchored emergency anchors with its components, calculating the road slab through the equivalent method of concrete road slab combined with structural mechanics, analyzing the stability of this emergency repair technology, proving that this kind of emergency repair technology can be applied in the actual situation of the emergency, enriching China’s repair methods of water damage to the roadbed, and meeting the strategic needs of the transportation construction.
