Monitoring for Successful Site Improvement

Ground Improvement by Deep Vibratory Methods

“…Modern data acquisition systems for vibro replacement collect, store, and display all relevant data of a stone column including column identification number and, as a function of real time, depth, AC current or hydraulic pressure of the vibrator motor, stone volume (measured directly or deduced from measured stone weight), air pressure, and installation duration. All data are generally collected numerically and can be stored or used for graphical displays to support construction and supervision procedures or to serve for quantity surveying purposes (Bauldry et al, 2008). Interpretation of the graphical printouts obtained in this way is very important but requires experience.…”
