Subsidence observation:-Monitoring equipment: tables measuring subsidence 80x80cm cross-section, is connected to the long bar made of steel tubing and the protection indicated on the drawing. The length of each bar must be accurate so long as 1 m.-On each cross-section measuring table 3 disposition of surface subsidence, put on layers of geotextiles separated.-Measurement time: begin measuring from the base up to the unloading.-Measuring frequency 1 time/day in the time up, 7 days/times during the wait.Data processing:-Establishment of metrics: setting the chart the process up and compress process respectively (around the same time) for each table to measure subsidence.-Conduct trials under the supervision of the engineer.
