Landscapes and real estates are becoming very expensive day after day incorporated with the explosive increase in populations. Leaving a property estate due to poor soil engineering properties is not an option today. This will open tremendous doors to find solutions to increase the bearing capacity, reducing settlement by increasing soil strength properties. The trend of solutions can go in two directions, one direction as to stabilize in-situ soil, while the other goes into changing foundation configuration such as to use deep instead of shallow foundation and using the screw piles will settle into the second option. Using the helix piles is rather considered a fresher technique compared to the conventional piles. The mechanism of the screw piles is complicated same as the ordinary piles, but with the same objectives. This research is concerned to show the improvement obtained in using the helix and bulb pile techniques in improving the carrying capacity of conventional piles in soft clay. As such a laboratory model is utilized having dimensions of 30cm diameter and 55cm height. Three types of piles (screw, conventional and bulb) are used in this study. Test results reveal that by far the helix-type pile is more superior in providing higher bearing load capacity and stiffness compared to the bulb piles and the conventional ones. Double-helix increased the load capacity compared to conventional pile by about six times, for single about 3.5 times measured at limiting values. For stiffness 10 times and 6 times are recorded. Double bulb increased loading capacity by 3.5 times and 2 times for single bulb. About stiffness, the increase is 2.5 and one time respectively. [ABSTRACT FROM AUTHOR] |
