Client requirement
Tilt correction and foundation strengthening addressed differential settlement and overall tilt of high-rise housing.
Engineering challenge
Settlement rate, displacement and forces changed throughout correction, requiring adjustments based on monitoring.
Technical approach
Borehole soil extraction, jacked pipe piles and compaction grouting stabilized settlement at selected locations before controlled-settlement correction and overall foundation strengthening. Computer-based stress and strain monitoring supported control.
Project value
The work staged settlement stabilization, controlled-settlement correction and dynamic monitoring.
