| Abstract | Evaluating the actual diameter of jet grouted columns plays a significant role in determining the success of the jet grouting technology. An acoustic monitoring system capable of directly recording the sounds due to the erosion of soil from the jet grouting, detected at different distances from the jet nozzle was used to determine the diameters of the jet grouted columns. Although this acoustic monitoring system has been utilized by a number of researches in the world, further jet grouting acoustic data from various sites and soils are required to establish an acoustic database for future jet grouting work to estimate the effective diameters of jet grouted columns formed in the particular site. However, this system was first introduced in Thailand on Bangkok soils. Therefore, this study was conducted for the MRTA Orange Line Project in Bangkok, Thailand to determine the effectiveness of this system on the Bangkok soils. The average threshold peak amplitudes and the standard deviations calculated from the acoustic data of trial test columns were used to define the effective diameters of jet grouted columns formed in Bangkok soils for the future jet grouting practices. |
