Steel Pipe Pile

In recent years, more and more large-diameter and super-long steel pipe piles are applied in engineering project. But people just know little about the bearing characteristics of super-long piles as it is very difficult to study such type of super-long piles in the laboratory and the accumulated test data of super-long piles in actual projects is very few restricted by test conditions and test cost. In engineering work, design value of bearing capacity of large-diameter and super-long piles is still referred to the calculation theory of ordinary pile that cannot take into account engineering security and economic simultaneously. In this paper, SVM-Q which is an intelligent algorithm based on Support Vector Machines is developed for predicting side friction of large-diameter and super-long steel pipe pile. Result shows that the side friction of longer large-diameter and super-long steel pipe piles with similar bearing characteristics can be effectively predicted by the SVM-Q algorithm after fully learning enough side friction data samples of the limited testing piles with gradually larger length, and boundary length of super-long steel pipe pile in this actual engineering could be qualitatively judged by comparing predictive data with the measured data. This method is very meaningful for initiative predicting the bearing capacity of large-diameter and super-long steel pipe piles in the case that there is no suitable calculation method. The predictive bearing capacity also can be adopted to verify the bearing capacity of large-diameter and super-long steel pipe piles that donot be field-tested by static load tests in actual projects.

Long Kali is a sub-district of Paser Tana Paser Regency Prov. East Kalimantan. In this sub-district have two village separate by a river, that is Perkuwen river, there is bridge has a broke. Whereas the village very needed a bridge because it is used as a transportation infrastructure for peoples and also passed by vehicles transporting oil palm yields . Therefore, the design of composite bridges made with spans 25 m and 7 m wide bridge.In this plan the analysis of Standard methods of loading refers to the bridge imposition For RSNI T-02-2005 about composite bridge structure design method, refers to RSNI T-03-2005 about Steel Structural Design For Bridge, SNI 03-1729-2002 about Steel Structures Planning Procedures and SNI 03-2847-2002 about Concrete Structures Calculation for Building.The result is used the main girder profile SH 950 x 400 x 16 x 32 and diaphragm WF 400 x 200 x 8 x 13. Vehicle floor plate thickness 20 cm using quality concrete  30 MPa and quality reinforcing steel reinforcement  360 MPa with subject dividers reinforcement D22- 100 and D12-100 mm. In using concrete pavement  30 MPa D22-100 mm staple reinforcement and shear reinforcement rebars quality D12-100 mm  360 MPa. Concrete abutment in the form  25 MPa at 2 m height and length of 8,5 m. Steel pipe pile foundations quality  25 MPa are 16 pieces with a length of 10 meters and a diameter of 0.4 m.Keyword: Bridge, composite, steel pipe pile.

Assembled steel pipe pile, which is a novel pile foundation, is developed in the paper. The ultimate uplift bearing capacity of the pile is proposed, and simulation by Plaxis3D and the corresponding experiment are performed to verify the theory. In the simulation, ultimate uplift bearing capacity of the assembled steel pipe pile and ultimate lateral frictional resistance of the interface of pile-soil increases with the increasing of the strength and stiffness of the interface of pile-soil, and with the increasing of length-diameter ratio, ultimate uplift bearing capacity of the assembled steel pipe pile increases while the ultimate lateral frictional resistance decreases gradually. The ultimate lateral friction is influenced by both of the strength of the soil around the pile and the interface of pile-soil, and the ultimate uplift bearing capacity obtained by simulation and theoretical calculation are close. Long-gauge FBG sensors are used in the experiment for measuring the longitudinal strain of the pile, and the error of ultimate uplift bearing capacity between the results of experiment and theory is less than 10%.
