| Abstract | This thesis presents the effectiveness of a large diameter jet grouting technique for installation of jet grout piles for tunnel construction in Bangkok. The traditional size of the jet grouted piles that are used in Thailand is up to approximately 0.8 - 1.5 m. The large diameter jet grouting technique can be utilized to form jet-grouted piles with a diameter up to approximately 3 m using a double-tube jet nozzle with a high flow rate of 360 l/min and a jet grouting pressure of 35 MPa. The advantages of using the large diameter jet grouted technique instead of the traditional methods include, but not limited to, minimize the number of boreholes, save time, and provide higher strength and lower permeability of the treated materials. The procedure of the large diameter jet grouting technique was provided in the thesis. The required design parameters for the grouted materials were verified by conducting laboratory testing of coring samples obtained at the site. Moreover, the required design parameters were further verified by conducting a jet wave monitoring test and an electrical resistivity test at the site. The results of the laboratory tests and the field tests indicate that the design requirement of the treated materials can be met effectively using the large diameter jet grouting technique. |
