Construction of 2 reinforced concrete wharf supported by steel piles founded on rock - construction of duc-d~albe each consisting of a steel tube pile
surmounted by a metal platform and equipped with a defense of berthing - construction of mooring berths - supply and installation of mooring and berthing equipment (fangs, winches, ladders, buoys, berths).
The test results show that the double grouting technology can reinforce the soil between piles and improve the mechanical performance of the steel floral tube group as well as improve the horizontal bearing capacity of the steel floral tube pile.
Therefore, double grouting increases the capacity of the steel tube pile to resist horizontal thrust.
(2) The technology of the double grouting improves the mechanical performance of the pile group and the horizontal bearing capacity of the steel floral tube pile. Compared with traditional single grouting, the horizontal bearing capacity of the single pile with double grouting increased by 24.4%.

In GB50396-2014 , [theta] means the hoop coefficient of concrete-filled steel tubular members [mathematical expression not reproducible] represents the steel content of concrete-filled steel tubular members, in the design of compressive strength of concretefilled steel tube piles
, B and C are the influence factors of the cross-sectional shape on the hoop effect, and about circular cross section, B = 0.176 * f/213 + 0.974, C = -0.104 [f.sub.c]/14.4 + 0.031.
Based on a reduced scale, the slender pier specimen was built, consisting of six steel tube piles, a concrete-filled steel cap, and a reinforced concrete pier body, as shown in Figure 4.
As illustrated in Figure 8, the 8-node shell finite elements programmed in ADINA are used to model the steel tube piles, and the 20-node solid finite elements are used to model the rest of the specimen including the pier body and pile cap.
The trestle sections were secured by means of 116 steel tube piles
driven 70 to 80 meters into the now-stable foundation below and connected to each other.
