Bearing Properties of Large-Diameter Embedded Rock-Socketed Pile with Steel Tube in Frame Wharf

The embedded rock-socketed pile with steel tube in the current structure of the form has more and more widely used in recent years in the deep water pier and cross river bridge in the use of more frequent. With the rapid development of deepwater wharf construction, large diameter steel tube embedded rock piles have been widely used in the foundation of vertical Wharf in inland river frame. Steel casing and reinforced concrete inner core are two parts. Steel tube outer tube is mainly in the construction measures to ensure that the pile and the inner core of the reinforced concrete part is used as a pile to transfer. In this paper, based on the second phase expansion project of Port Orchard Operation District of Chongqing, through indoor single pile of physical model tests and with the corresponding physical model test results, the Inland River Wharf frame steel casing of rock socketed pile foundation under vertical loads and transverse effect of the working mechanism and mechanical properties was studied, for frame wharf steel protecting tube embedded rock pile design research lay a technical foundation.
