PILE HORIZONTAL DISPLACEMENT MONITOR INFORMATION CALIBRATION AND PREDICTION FOR GROUND FREEZING AND PILE-SUPPORT FOUNDATION PIT

摘要

Monitor data of pile horizontal displacement for Ground freezing and Pile-support Foundation Pit of south anchorage of Runyang Bridge, had Obvious error by freezing and deformation of bottom part. It was proved that horizontal displacement of pile-top beam can't be used to Calibrate error, but the displacement Calibration on Position of first support could be used to Correct pile horizontal displacement. The displacement on Position of first support was calibrated by data of support force and temperature. This result provided reliable monitor data for Anti- analysis and prediction of foundation pit, and the experience was backlog for construction of similar engineering aftertime.
