| Abstract: | Taking Pier 56# of steel sheet pile of Qiupu Bridge on Nanjing-Anqing Railway as an example, the calculation method and design construction for protection of deep foundation pile with steel sheet pile are introduced and the construc-tion process （entrance, excavation, support, plugging） prone to problems are discussed and relevant solutions are pro-posed. The feasibility of the program is proven through the use of software to calculate the stress of steel sheet pile and stress on support. |
