If you're referring to the embankment slope next to the road, it's normally 1:2 or flatter. Experience and observations suggest that the instability of slopes in most cases shows as sliding mass of soil, the slid-ing body, in a straight or curved sliding surface. SEACAP 21/004 Landslide Management Unretained fill/embankments tend to fail because: Embankment side slopes are too steep, There is inadequate embankment drainage, Of erosion of the slope immediately below the embankment Inadequate foundation surface preparation ,vegetation or topsoil left in place, lack of benching Planes of weakness in ground below embankment e,g pre- The prescribed sloping angles and bench dimensions can be determined by using any of the following options: 1. Shoulder and side slope design are also very important like pavement design because the stability of a road depends on them also. A culvert along the city’s Leubethaer Straße could no longer handle the enormous quantity of water. if the designed height of the embankment is 6.0 m, the embankment of 6.6 m height should be constructed initially to allow for the settlement of soil at a later stage. Fig-1 Surface drainage in Road embankment 3.2 Road in cutting When the road is in cutting the drains are provided on either side of formation in Fig-2.In these case the drains just after the edge of formation. The proposed alignment runs along the bank of the river Yamuna and there is a barrage towards the downstream side slope of the river. The height of embankment is varying from 3 to 5 m and side slope is 2H:1V. For very soft subsoils less steep side slopes should be considered in order to reduce loads on the subsoil and prevent excessive settlements. (See Figure 04-9.) Slope failures lead to loss of life and damage to property. 1. For fills with normal side slopes of 1:1.5 or 1:2, the side slope of the EPS fill should not be steeper than 2:1, see fig. (a) The headcut migration process of a side slope due to hydraulic soil erosion during thebreach widening process. Here is a cross-section view of a road that shows the daylighting of a 3:1 slope on either side. The bridge approach embankment also includes any embankment that replaces unsuitable foundation soil beneath the bridge approach embankment. The side slope height is 1.05-3.5meters.

Reducing the side slope of the embankment can increase the usable space on either side. EXCAVATION AND EMBANKMENT. 2.00 – 3.99 1:2. (b) Sketch of a headcut and coordinate system of an eroded notch.2.2. Berms are considered in each side of slope and width of berms is 2m. Measures such as stone pitching, gabions and placing soil-cement layer have been used to protect road side-slopes. When the road is on embankment, the surface water to flow across the shoulders and down the side slope to the side drains. Side slopes are properly protected by grass so that erosion of side slope does not take place. The flow of water from the road surface is well distributed to give a uniform flow of water. Figure 2: Typical cross-section of a side cast road embankment fill (after Musser and Denning (6)) and slope geometry Figure 3 shows photographof two roadways s on steep hillsides in the States of Earthwork Calculation for Road. The slopes are subjected to soil erosion from natural erosive forces and climatic conditions, particularly torrential rains and strong winds. The embankments are provided with a 1:2 or 1:1.5 (V:H) side slopes for the stability of embankment. Downstream or upstream berms can be used to help achieve stable embankment sections. Retaining walls come in two forms, but all involve a process where rocks are stacked and placed in the formation of a wall to help keep soil in place. Embankment is a synonym of slope.

To determine whether the inlet is submerged, we first calculate 5 and above Determine from detail slope stability analysis Reference: • SMALL SCALE WATER RESOURCES SUBPROJECT PLANNING AND … CDG weight exerted on the road embankment affected both horizontal and vertical movements. The intersections of slope planes in the highway cross section should be well rounded for added safety and increased stability of out-of-control vehicles. (This is the angle α opposite the "rise" side of a triangle with a right angle between vertical rise and horizontal run. 3. The road was planned to be realigned to the hill side to avoid disturbance to the site. Embankment Slope (Fill Slope): The fill (embankment) slope beyond the surfacing taper, or clear zone hinge point for barn roof design, that extends outward and down until it intersects the existing terrain. A circular concrete culvert has a diameter D = 3 ft, a slope of S = 0.025, and a square edge inlet with a headwall. downslope, or frontslope side, of the toe-of-fill keyway, as sketched here.
