2、 Project introduction * * Bridge is located in * * Group, Tushan Village, Xiayang Town, Yongchun County, Quanzhou, spanning Liangshan'ao Liushuigou and civilian buildings, with mileage chainage of K111+654.67 ～ K111+903.33, the whole bridge length of 248.66m, the longitudinal plane of the bridge is located within - 2.523% of the straight line, and the left plane of the bridge is partially located in the straight line, partially in the transition curve with Ls=160, and partially in the transition curve with R=760; The right plane is partly located in a straight line, partly in the transition curve with Ls=150, and partly in the transition curve with R=730. 　

The total length is about 15.6 km, of which the bridge is about 4.744 km long, the south bank connection is about 3.083 km long, and the north bank connection is about 7.773 km long. The highway standard is adopted for the whole line of the bridge, with the design speed of 100km/h, the design load of vehicles - over 20, and trailers - 120.

Project content and scope: the bridge starts at K38+520.68 and ends at K38+804.92, with a total length of 284.24m. The bridge aperture is (71+128+71) m prestressed concrete continuous rigid frame. The content is detailed and can be used for reference. 　　

The design range of this section is from 0+000.00 to 0+920.00, with a total length of 920.00m, belonging to Class II highway. The bridge works are 567.32m long, and the approach roads on both sides are 352.68m long. The content is detailed and can be used for reference.

2. Design standard According to the requirements of the assignment, the design load of this bridge is steam level 20 and hanging level 100. The bridge is 7.5m wide and the carriageway is 6.5m wide. Cement concrete deck is adopted. 3. Geology of the bridge site The landform of the bridge site belongs to the intermountain valley landform, and the terrain elevation varies from 37.00m to 45.00m. The two banks are the alluvial terraces of the Xinxing West River. Because of water storage and power generation, the water depth is always about 3.00m~4.00m. Stratum characteristics at the bridge site are Quaternary alluvium (clay, loam and round gravel) and Cambrian sedimentary rock (weakly weathered sandy shale, strongly weathered sandstone and weakly weathered sandstone) from top to bottom. The seismic fortification intensity of the site is 6 degrees, and the design basic seismic acceleration value is 0.05g. 　　

Change all dry joints to wet joints. 450 dry joints are reconstructed for the whole bridge. 150 wet joints were added to the old bridge. The concrete on both sides of the diaphragm joint shall be chiseled away to expose the reinforcement, and the short reinforcement shall be overlapped welded. The reinforcement formwork shall be used to pour the micro expansion concrete prepared by UEA expansion agent to ensure the compactness of the joint concrete. In case of defects after formwork removal, Oak mortar can be used for repair. See the drawing for overlapping reinforcement. Including plan, elevation, section view, bridge deck pavement, continuous joint structure diagram, dry street moisture exchange joint structure diagram, steel expansion joint diagram, drain hole structure diagram, old bridge added middle diaphragm diagram

A complete set of design drawings (ordinary reinforced concrete cast-in-place box girder) of a curved bridge on a Panshan highway has 138 pages in total.
