SURVEYING (UPVOTE WILL BE GIVEN. PLEASE WRITE THE COMPLETE SOLUTIONS AND DIAGRAMS *IF NECESSARY* LEGIBLY. NO LONG EXPLANATION NEEDED. ANSWER IN 2 DECIMAL PLACES AND BOX THE FINAL ANSWER.) 2.A compound curve connects the first, middle, and last tangents with azimuths 172°, 190°, 202° (reckoned from South line). The length of the long chord connecting PC and PT is equal to 300m. Station of PC is equal to 5+410. If the long chord is parallel to the Common tangent having an azimuth of 190° (middle tangent), solve the following: A. Station of PCC B. Total length of the compound curve (LCC) C. Station of PT
1. Given are the stations and elevations of a proposed symmetrical parabolic highway curve. POINT A B с ELEVATION (m) 93.60 90.00 96.48 STATION 6+075 6+255 (PI) 6+435 Note: Lines AB and BC are the tangent lines of the proposed highway curve. The curve will clear a boulder at Sta. 6+276, and the elevation of the tip of the boulder is 92.65m. Solve for the ff: a. length of the symmetrical curve b. stationing and elevation of PC c. A circular pipe culvert is to be laid out as part of road drainage requirements. If the elevation of the invert of the culvert is 90.25 m., determine the volume of earthworks needed to cover the culvert considering a 20% shrinkage factor for the backfill. The culvert has an inner radius of 0.4 m and thickness of 0.1 m. Consider 1 m width of the road section. 2. Suppose that during the construction of the symmetrical curve in problem #1, it was discovered that left side of the grade intersection falls on a rocky terrain. To avoid additional cost of excavation,…
