EIA for the proposed Hulhule-Male’ Bridge Project
Concrete structures are as follows:
Carriageway: 5 cm bituminous concrete + 10 cm asphalt macadam base +20 cm gravel-sorted
subbase +15 cm coral sand cushion;
Sidewalk: 20 cm cement concrete +45 cm coral sand cushion.
2.3.2.4 Design scheme of piers and foundation
There will be a total of 26 bridge piers (No.1 to No.26) and 2 bridge abutments (No. 0 and No.
27). The cast-in-situ bored pile foundation is adopted uniformly for all bridge piers and
abutments. The scheme for all bridge piers and foundation is presented in Appendix C.
No. 0 abutment of the Male island side shall adopt pier foundation with a 1.5 m diameter.
No. 1 to 10 pier bodies are T-type piers, with 2.0 (axial direction) × 4.0 m (transverse direction)
of sectional dimension. The pier foundation scheme is planned to use 4 cast-in-place piles with
1.5 m of diameter, and bearing platform is 2.5 m high, with 6.25 (axial direction) × 7.0 m
(transverse direction) of plane dimension.
No. 11 to 17 pier bodies are T-type piers, with 2.0 (axial direction) × 4.0 m (transverse direction)
of sectional dimension. The pier foundation scheme is planned to use 6 cast-in-place piles with
1.5 m of diameter, and bearing platform is 3.0 m high, with 6.25 (axial direction) × 10.0 m
(transverse direction) of plane dimension.
No. 18 pier is the transition pier of the main bridge, the pier body is T-type pier with 3.0 (axial
direction) × 4.0 m (transverse direction) of sectional dimension. The pier foundation scheme is
planned to use 6 cast-in-place piles with 1.5 m of diameter, and bearing platform is 3.0 m high,
with 6.25 (axial direction) × 10.0 m (transverse direction) of plane dimension.
No. 19 to 21 pier bodies are V-type piers, which are fastened and connected to the top box
girder. Main pier No. 19, 20 and 21 shall have 12 variable cross-section bored piles with
diameters ranging from 2.5 m to 2.8 m; the bearing platform is rectangular, with an overall
dimension of 17.0 (axial direction) × 23.25 m (transverse direction).
The box girders at Pier No. 22 to 23 are directly fastened and connected with the bearing
platform, without the pier body. Main pier No. 22, and 22 shall have 8 variable cross-section
bored piles with diameters ranging from 2.5 m to 2.8 m; the bearing platform is rectangular, with
an overall dimension of 10.75 (axial direction) × 23.25 m (transverse direction).
