Analysis of calculation results of studying the stability of slopes when the tension load in the embankment subgrade
Design characteristics for the stability of the slopes of the subgrade. The steepness of slopes of embankments up to 3 m high on category I-III roads should be assigned taking into account the safe driving of vehicles in emergency situations. An analysis of the values of the design characteristics of the steepness of the slopes shows that the design characteristics in the irrigated zone, when the groundwater level increases and impacts in the subgrade, aggressively acts in the spring period of road slope stability. During the research, it was found that the slopes of all pickets, at a load of 0.15 MPa, where the height of the embankment H=2.0 m are stable, if you do not take into account the impact of capillary water, soil saturation in the embankment. At a load of 0.20 MPa, all pickets with an embankment height of h< 2.0 m are unstable in the capillary water-saturated state.
