Model tests on reinforced sloped embankment with denti-strip inclusions under monotonic loading
Abstract Denti-strip inclusion is a new type reinforcement that consists of conventional strip type reinforcement and vertical inclusions which are installed on the strip in spacing. A series of laboratory model tests were carried out on a physical model of reinforced sloped embankment with strip inclusions and denti-strip inclusions under surcharge. Compared with strip reinforcement, it is found that due to the existence of vertical reinforcing elements which provided passive resistances against shearing and enhanced soil strength, denti-strip inclusions are more effective in improving the ultimate surcharge, reducing the settlement and restricting the lateral displacement of the slope. Furthermore, the shear bands in the embankment reinforced with two-layer inclusions under the condition without cutting of reinforcements are separated into several discontinuous arc bands by the inclusions unlike the single continuous arc in unreinforced embankment; the inclination angles of the shear bands are greater than that of unreinforced embankment and the position of the lower arc is close to the mid-height of embankment.
