| Abstract: | Based on the project of Pier No. 4 of Liushui River Right-Line Bridge in Xiang-Yu railway, mechanical effects during the construction of steel cofferdam are analyzed using finite element. Stability condition and deformation state of the construction are researched, with some significant results, which can provide data for construction and optimal control scheme. In addition, test research is made to the steel cofferdam. The calculation results are close to the results of the test, proving the correctness of the calculation model. Not only does it provide a guidance to the calculation and design, but it can also act as a theoretic reference for the design and construction of similar projects later. |
