TY - JOUR ID - TI - Effect of Embedment and Spacing Ratios on the Response of Lateral Load of Single and Group Piles AU - Aya H. Chalob AU - Mohammed H. Al-Dahlakib , AU - Mohammed A. Al-Neamia, PY - 2021 VL - 39 IS - 7 Engineering & Science SP - 1144 EP - 1152 JO - Engineering and Technology Journal مجلة الهندسة والتكنولوجيا SN - 16816900 24120758 AB - This paper displays an experimental work of three-scale model tests of single pile and nine–scale model tests of group pile (1x2) with spacing to diameter (S/D) ratios (2,4, and 6) respectively. The pile models inserted in the medium-dense dry sand with a relative density of 60% and different length to diameter (L/D) ratios (15, 25, and 30) were subjected to the lateral load with a rate of 2.5 mm/min. The test results present the effect of the change of the ratio of (L/D) and (S/D) on lateral displacements at the head of the pile. For single and group piles when the embedment ratio (L/D) increases, the ultimate lateral load increases also for group piles. When the (S/D) ratio increases, the ultimate lateral load increases. However, for (L/D) equal to 20, this increment is not linear with spacing increment, where a slight increment is observed of the relatively close pile and vice versa. While for other (L/D) ratios the increment of pile load is increased linearly with spacing increase.
