The Pier Foundation Design of the Beijing-shenyang Passenger Line Liaohe Super-large Bridge

In recent years, with the rapid economic development of the China, the railway construction also experiences a fast growth. State Department adopts The Twelfth Five-Year Plan of Transportation in 2012, and plans to build a batch of great railway projects. The construction program of Beijing-Shenyang Passenger Line is one of them. The main content of this article is to design the pile foundation of the Liaohe Bridge in Beijing-Shenyang Passenger Line. Using the large diameter bored piles, and design the pile foundation in detail according to the standard, including the settlement of pile, the bearing capacity and the design of the pile caps. Furthermore, it also used FLAC3D to simulate. Through the comparison of simulation results and calculation results, it found that simulation of the ultimate bearing capacity of the pile has little different than the calculation results, the error is 7.1%, settlement rule is also consistent with reality, but the settlement has certain differences, the error is 63.5%. Overall the results of the numerical simulation have played a certain reference role for the design of pile foundation. Keywords—bored piles; Pile foundation design; Numerical simulation
