Abstract：The super-large highway bridge is an important part of connection construction of the outer ring way in Wuhan City. The bridge abutment No.0 sits on the foundation of rock-socketed pile groups embedded in thick soft groundsill. A high soil backfilling bank reinforced by powder-spray piles and geogrid is located to the south of the bridge abutments. The abutments became tilting not only in the north but in the west direction because of the unsymmetrical backfill and two times of landslides of the high road bank. The main rectification schemes of stress release and horizontal loading lead to a good result—the bridge abutments resume their original functions and bring about good social and economical benefits. The rectification of the bridge abutments provides some references for the similar structures with oversized rock-socketed pile group foundation.
