Question

A
-6.00% grade and a +2.00% grade intersect at station 20+00. The two
grades are to be connected by a vertical curve 400 ft long. The
elevation of the BVC is 348.52.

What is the...

a. Elevation on the curve of the low/high point?

b. Elevation of the curve at station 19+00

c. Elevation of the tangent at station 21+00

d. Elevation of the curve at station 21+50

e. Elevation of the curve at station 18+50

Answer #1

A 3.0% grade passing at station 20+00.00 at an elevation of
99.10 m meets a -2.0% grade passing at station 20+50.00 at an
elevation of 99.60 m. Please note that these two elevations and
stations DO NOT correspond to BVC and EVC.
a) Determine the station and elevation of the point of
intersection of the two grades.
b) If the highest point on the curve must lie at station
20+55.00, find the elevation of this point and the length of...

The PVI of a vertical curve is at station 110 + 00 and elevation
1100.00 ft. The vertical curve is equal tangent, 600ft long, and
connects an initial grade of +1.30% and a final grade of –1.10%.
The vertical curve crosses a 3ft diameter pipe at right angles. The
pipe is located at station 112 + 00 and its centerline is at
elevation 1093.00 ft.
a) Using offsets, determine the depth, below the surface of the
curve, to the top...

the tangents at full stations g. (2 pts.) Tangent offsets at full
stations h. (2 pts.) High/low...

Given: L=200 ft equal tangent parabolic curve with g1
= -1.25%, g2 = +1.25%, VPI station = 146+00, and VPI
elevation = 1,895.00 ft.
a. Compute stationing of BVC.
b. Compute stationing of EVC.
c. Compute rate of change, r.
d. Compute elevation of BVC.
e. Compute elevation at Station 145+50.

Please I need The right answer for this question as soon as
possible.
A sag vertical curve (equal tangent) has PVI at station 212+00
and elevation 540.75 ft. The initial grade is -2.5% and the final
grade is +4.5%. The length of the curve is 900 ft. Determine the
following,
1. Stationing of the low point, PVC, and PVT.
2. Elevation at station 213+00, PVC, low point, and PVT.

An equal-tangent crest vertical curve is being designed for a
speed of 55 mph. The curve connects grades of 2% and -3.5% in the
direction of interest. The curve high point is at station 110+00
and has an elevation of 500 ft. What is the station and elevation
of the PVC and the PVI?

A vertical parabolic curve is to connect a back tangent of -3%
and a forward tangent of +4%. The change of grade is 0.60% per 20 m
station. The stationing of PC is 17+428 with an elevation of 200 m.
Compute the:
a) length of the parabolic curve;
b) stationing of PT (format: 00+000.00);
c) elevation of PT;
d) elevation of the lowest point of the curve;
e) elevation at Station 17+544.67.
