PROBLEM
Two simple curves having angles of intersection of the tangents equal to 36° and 68°45' respectively are joined
to formed a compound curve where the P.T. of the first curve now becomes the P.C.C. of the compound curve. If
the length of chord of the first curve is 472.14 m. and the length of chord of the second curve is 235.21 meters. From
the given data of an earthwork between PC and PT (STA. 20+240) assuming both have same slope and base of 6
meters determine:
STA. PC
1. Length of Tangent of the first curve
+1.40
+2.50
+1.20
2. Length of Tangent of the second curve
6.40
4.8
3. Radius of the Second curve
4. Station of PC
STA. PT
5. Station of PI
+2.40
+1.50
+2.30
6. Volume of the earthwork by End-Area Method
5.20
6.20
7. Volume of the earthwork by Prismoidal Formula
8. Corrected Volume
