Nowadays the development of the human societies necessitates the reclamation of lands for the construction of airports, buildings etc even on marshy lands. For construction of structures on soft soils, stabilization is necessary to avoid of unusual settlements and improve the soil strength. One of the suitable methods for the improvement of soft soils is using geotextiles. Using geotextiles with drainage and reinforcement capabilities, the rate of soil consolidation may be speed up and the soil bearing capacity improved. In this research study the effects of a combined geotextile and fiber reinforcement of a very soft clayey soil on speeding up its consolidation process and improving bearing capacity were considered. The effect of parameters such as the number of the reinforcements in a certain area (different reinforcement arrangements), the length of reinforcements in a given arrangement and also the direction of reinforcements in a certain arrangement and length on the consolidation process and bearing capacity of the selected soil were investigated. The required experiments were performed in three steps. In the primary step, a number of one-dimensional standard consolidation tests was conducted to select a suitable soil for this laboratory study. In the second step, several tests were carried out in a relatively large scale in order to consider the effects of the reinforcements in different arrangements, directions and lengths on the soil consolidation and bearing capacity. And finally in the third step a number of complementary experiments (similar to previous step expect for making some modifications in the reinforcements) were carried out. The results of the conducted tests showed that the consolidation time decreases with increasing the number of the reinforcements in all considered arrangements. However the rate of decrease of consolidation time in arrangements with 9 and 13 reinforcements was slowed down and approached to a nearly limit state. The tests results showed that the bearing capacity increases with increasing the number of reinforcements from 4 to 6. The bearing capacity, however, showed to decrease as the number of reinforcements increased to 9 and more. Changing the reinforcement directions from vertical towards beneath the reinforcing area, the consolidation time increased. Conversely changing the reinforcements directions towards outside of reinforcing area, the consolidation time decreases. Also every deviation of reinforcements from vertical direction (till 45 angle), either into the beneath of reinforcing area or outside of it caused a decrease in the bearing capacity. Also it was observed that consolidation time decreases with increasing the length of reinforcements. ..............................
