MONITORING TECHNOLOGY IN INFORMATION-BASED CONSTRUCTION OF DEEP PIT WORKS IN SOUTH ANCHORAGE FOUNDATION OF WUHAN YANGLUO YANGTZE RIVER BRIDGE

On account of the complicated geological condition, deep excavation depth, too many brackets, big construction difficulties and lack of previous experiences, a strict monitoring system must be established in the construction organization design and implemented in the construction of the bridge foundation so as to analyze and process the measured data in time. In the information-based construction of the deep pit excavation, construction measures, sequences and steps were timely adjusted through optimization on the base of monitoring data, ensuring to carry out the construction smoothly.
