摘要
以宁安铁路秋浦河特大桥56#墩为例,介绍了水中承台深基坑防护利用拉森钢板桩施工的施工工艺及设计计算方法,阐述了施工过程中各个环节(打入、开挖、支撑、堵漏)容易出现的问题及解决方法,利用软件计算分析钢板桩及支撑的受力情况来证实方案的可行性。
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.
