Although the cement-treated marine dredged clays have been used as filling materials for construction or reclamation, many of previous studies were more applicable to soft foundation improvement methods such as deep cement mixing and jet grouting.
This specific scheme mainly comprises following steps, i.e. ground improvement behind abutment, foundation pit excavation under bridge deck, underpinning pile with raft and cutting pile with shield machine directly, etc.
