Abstract

         One of the most significant technologies for usage in civil engineering projects is sheet pile walls. Applying sheet pile walls with anchors limits  sides excavation to a depth of more than six meters. The effects of a lateral displacement sheet anchored pile wall on sandy soil under a 10% Cyclic Load Ratio (CLR) and for 100 cycle’s number were investigated experimentally in this study.

         This study examined the effects of different parameters on cantilever and anchored sheet pile wall stability under periodic load. The parameters which are studied: the ratio of spacing between anchored to free height of sheet pile wall (S/H= 1/3, 2/3, and 1), ratio of anchored length to free head of sheet pile wall (L/H= 1, 4/3, and 5/3), distance of strip footing from sheet pile wall (D/H= 1, 1/2, and 1/4)  and  inclination rods angle (ϴ= 0^o, 10^o, 15^o, 25^o, and 30^o) under influence of two–way cyclic lateral load at 0.2 Hz frequency. Lateral displacement of sheet pile wall as well as the total settlement of strip footing and tilting are recorded during the test.  When used the wale for sheet pile decreased the lateral displacement of a sheet pile to (66%, 20%, and 9%) as compared to values of lateral displacement without using wale for (D/H= 1, 1/2, and 1/4) respectively. The horizontal angle of anchors (ϴ= 0^o) supplied the reduction 89% in lateral displacement of the anchored sheet pile wall as compared the value of lateral displacement of cantilever sheet pile for length of anchored rod (L/H= 5/3) with spacing between two anchored rods to free height of sheet pile wall (S/H= 1/3) for distance (D/H= 1/2), but the angle (ϴ= 30^o) of length of anchored rod to free height of sheet pile wall (L/H= 5/3) reduce the lateral displacement about 98% as compared to cantilever sheet pile wall’s lateral displacement. The angles of anchors (ϴ= 10^o, 15^o, and 25^o) with the length anchored rod to free height of sheet pile wall (L/H=4/3) with spacing between two anchored rods (S/H= 1/3) and distance from strip footing to free height of sheet pile wall (D/H= 1/2) provided reduction in lateral displacement of the anchored sheet pile wall (92.81%, 94.91%, and 96.79%) respectively. The total settlement of strip footing for distance from strip footing to free height of sheet pile wall (D/H= 1/4) is exceeded the allowable settlement, but for  distance from strip footing to free height of sheet pile wall (D/H= 1, and 1/2) is not exceeded the allowable settlement for all inclination angle rods. The tilting of strip footing for distance from strip footing to free height of sheet pile wall (D/H= 1) is not exceeded the tilting limit, but for distance from strip footing to free height of sheet pile wall (D/H= 1/2, and 1/4) is exceeded the tilting limit. The safe distance for total settlement of strip footing to free height of sheet pile wall is (D/H= 1, and 1/2).  But the safe distance for tilting of strip footing to free height of sheet pile wall should be more than (D/H > 1/2).
