Foundation: Because of the bearing layer is deep, and the bridge is not in densely populated areas, so using the square driven piles - Abutment structure: • Abutment with piles type, reinforced concrete 30Mpa, cast in place • Foundation: driven piles with cross-section 45x45cm There are 11 piles, estimated length is 46m, the official length of piles will be decided after complete the trial pile • After abutment, putting transition slab, reinforced concrete 25Mpa, 3m long Selected soil under transitional slab is compacted reach K ≥ 0.98 - Pier structure: • There are types of piers: Piers for approach span with lane: Using pier of round columns format, pile cap, body and capping are cast in place reinforced concrete 30MPa Pier body is columns diameter 80cm Pier foundation include 10 driven piles 45x45cm, estimated pile length is 46m, the official length of piles will be decided after complete the trial pile piers for approach span lane and lanes: Using pier of round columns format, pile cap, body and capping are cast in place reinforced concrete 30MPa Pier body is columns diameter 80cm Pier foundation include 12 driven piles 45x45cm, estimated pile length is 46m, the official length of piles will be decided after complete the trial pile Two piers (in water) of span 33m Using pier of dense-body format, reinforced concrete 30MPa Pier estimated pile length is 40m, the complete the trial pile length (2 piers bearing ship impact pressure): pile cap, body and capping are cast in place foundation include 32 driven piles 45x45cm, official length of piles will be decided after (See detail in piers and abutment drawings) IV.2 IV.2.1 Approach road Layout - Design principles • Routes are designed suit to design standards of road class VI delta, Vtk=30km/h • Limit clearance of permanent house and existing projects • Take advantage of existing bridge to ensure traffic use old road for local use My An bridge Working drawing Page 21/35 Trung tâm Tư vấn Ứng dụng công nghệ TEDI South • Connect approach road to the existing road to make sure that bridge is in use after finished - Design results: IV.2.2 • New alignment is about 75m upstream from the existing bridge as agreement on date March 10th 2010 • The intersection at the end point of alignment with the existing road: Design the curve R=15m at the edge of pavement Longitudinal Profile Design principles - Create a Longitudinal profile to ensure favorable conditions and safety for vehicles and drivers, thereby minimizing operating costs; - Ensure enough clearance for the existing road cross under bridge - End point of alignment is connected with the existing road - Ensure conditions of hydrology, hydraulics, and navigational clearance follow requirement and minimum standards regulated for road class Controlled levels: - According to hydrology report of My An bridge made by Transport Engineering Design Joint Stock Incorporated South (TEDI South) on May 2010, water level as follows: Water level as frequency (m) No Bridge My An H1% H2% H4% H5% +3,21 +3,12 +3,02 +2.98 H average +1,25 - The road design level must meet following conditions: • Road shoulder level is higher than water level as frequency, with design speed V = 30km/h, TCVN 4054-05, so frequency of road design is P = 4%, minimum road center line levels as follows: Hmin1 = H4% + 0,5m + Hcross-fall Hcross fall : height difference between center line and shoulder H cross fall = 1,5 x 5% + 1,75 x 2% = 0,11m Hmin1 = 3,02m + 0,5m + 0,11m = 3,63m • Bottom level of pavement structure must be higher than regular water level, with day of continuously flooded is 20 days for fine-grained sand embankment 30 cm, minimum level of the center line as follows: Hmin2 = H regular + 0,3m + HKCAD + H cross fall My An bridge Working drawing Page 22/35 Trung tâm Tư vấn Ứng dụng công nghệ TEDI South HKCAD: thickness of pavement structure HKCAD = 0,30m H cross fall = 1,5 x 5% + 1,75 x 2% = 0,11m Hmin2 = 1,25m + 0,3m + 0,3m + 0,11m = 1,96m • The existing level of PR no.846 is +3.42m, and the new approach road must be connect to it So, we suggest the design level of approach road must be equal with the existing level • Compare the calculated results, minimum level of embankment design follow condition of existing road: Hmin = +3,42m Design Results: Longitudinal profile bridge area is designed as follows: • • All slopes are
