State Plane Coordinate Systems

The state plane coordinate system (SPCS or SPS) is a collection of 124 coordinate systems or geographic zones prepared for particular regions of the U.S. Every state consists of one or more than one state plane zone, the boundaries of which generally follow the county lines. Inside the U.S., there are 110 zones in total, 10 more zones in Alaska, 5 in Hawaii, and 1 for Puerto Rico and US Virgin islands. The system is extensively used for geospatial and geographic data assembling by the state and local governments.

Question

Tension cracks only develop if the soil is fully saturated near the ground
surface.
The presence of water in the crack alone tends to increase the shear
stress developed along the slip surface shown in the figure above,
while reducing the effective stress component normal to the slip
surface.
When calculating the FoS against the slip surface shown above, the
soil shear resistance along the crack should be omitted whether the
crack is filled with water or not.

For the slope shown in the figure below, which of the following
statements apply (select all that are correct):
i
Crack filled
with water
Slip surface
Cracks observed at the surface behind the crest are generally due to
tension stresses that develop in cohesionless soils (coarse-grained
soils).

A cut slope was excavated in saturated clays as shown in the figure. The soil has a unit weight of 17 kN/m³ and an undrained shear strength cᵤ = 20 kPa. The slope make an angle of 60° with the horizontal. Assume stability number m = 0.185. Slope failure occurs along the plane AC with BC = 8 m. Which of the following most nearly gives the stability factor?
A long slope is made up of a cohesionless soil with the internal friction angle of 34°. If the water table rises to the surface of the slope, then determine the maximum possible value of the slope angle to get a factor of safety of 1.5. Take saturated unit weight as 18 kN/m3 and the unit weight of water as 10 kN/m3.
Figure 15.47 shows an infinite slope with H = 9.14 m and the groundwater table coinciding with the ground surface. If there is seepage through the soil, determine the factor of safety against sliding along the plane AB. The soil properties are Gs = 2.7, e = 0.8, β = 16°, ϕ′ = 21°, and c′ = 59.8 kN/m2.
Q.5 Figure 5 shows an infinite slope with H = 30 ft and the groundwater table coinciding with the ground surface. If there is seepage through the soil, determine the factor of safety against sliding along the plane AB. The soil properties are Gs = 2.7, e = 0.8, β = 16 ͦ, Ø = 21 ͦ, and c’ = 1250 lb/ft2 .
An infinite slope is inclined at 22 degree. A plane of failure has developed at depth of 8 m from the surface. Given dry unit weight = 18kN/m3, c’ = 12kN/m2, angle of friction = 23.5 degree and saturated unit weight = 23kN/m3. Calculate the slope factor of safety if: (i) water table exists far from the slip line
For the slope given below, consider the slip surface divided into thirteen slices. Based on the ordinary method of slices, calculate the Resisting Force in kN for slice #3 for long term conditions. (Acceptable tolerance = 4%). The geometry of slice #3 and the soil properties are provided in the tables below. The height of water at the middle of the slice is hw = 3.0 m hint:Given that the soil is partially saturated in Slice#3, the total weight of the slice (W) should be calculated by summing up the weight of the area that is below the water table (saturated soil) and the weight of the area located above the water table (moist soil).
For the infinite slope shown in Figure 15.46, determine the height, H, for critical equilibrium. Given: β = 27°, γ = 19.5 kN/m3, ϕ′ = 18°, and c′ = 35.9 kN/m3.
The factor of safety (upto 2 decimal places) of an infinite soil slope shown in the figure having the properties c = 0. ф= 35°, Ydry =15 kN/m³, Ysat =19 kN/m³
