Fundamentals of Surveying problem: Topographic survey conducted by SALCON shows that the centerline of a proposed road cross section crosses a small valley between station 10+022 (elevation 123.00 m) and station 10+060 (elevation 122.50 m). The stationing at the bottom of the valley is 10+037 (elevation 111.20 m). The grade line of the proposed road passes the ground points at the edges of the valley (station 10+022) and (10+060) and the section at any of these stations are three level sections. Width of road base is 10 m with side slope of 2:1. Assume that the sides of the valley slope directly to the lowest point from the edges. a) Find the cross-sectional area of fill at station 10+037. b) Compute the volume of fill from station (10+022) to (10+037). c) Compute the volume of fill from station (10+037) to (10+060).
