Experimental Study for the Behavior of Anchored Sheet Pile Subjected to Cyclic Load in Sandy Soil

الملخص

Excavation deeper than about six meters is restricted by the application of sheet pile walls with anchors. This paper examined the effects of different parameters on anchored sheet pile walls under a lateral cyclic load ratio (CLR) of 10% and several cycles equal to 100. It was fixed by two anchored piles horizontally and embedded in sandy soil. The ratio of the spacing between anchored to the free head of sheet pile wall (S/H= 1/3, 2/3, and 1) and the ratio of anchored length to the free head of sheet pile wall (L/H= 1, 4/3, and 5/3) under the influence of two–way cyclic lateral load at 0.2 Hz environmental frequency. The research aims to ascertain the rod's impact spacing and length anchored on the lateral and vertical displacement of the sheet pile, as well as the vertical displacement of surcharge (line load) applied to the surface. The wale for sheet pile decreased the lateral displacement of a sheet pile to 66% compared to lateral displacement without wale. Also, the results of the length rod to the free height of the sheet pile wall (L/H= 1) increased the anchored sheet pile wall's lateral displacement by about 55% from the cantilever sheet pile wall's lateral displacement with wale because it was near the active failure zone. The ratio of length to free head of sheet pile wall (L/H= 5/3) reduced the anchor sheet pile's lateral displacement wale by about 51% compared to the cantilever sheet pile's lateral displacement with wale. The ratio of length anchored to the free head of the sheet pile wall (L/H= 4/3) decreased the anchored sheet pile's lateral displacement to 49% compared to the cantilever sheet pile's lateral displacement with wale. Both reductions for two lengths with the spacing ratio between the anchors rod to the free head of the sheet pile wall was (S/H= 1/3).
