导管架大型化、深水化的发展趋势带来了更高的装船难度，对位于码头前沿的滑道块性能提出了严峻挑战，传统的水泥滑道块难以满足需求，需要设计力学性能更好的钢制滑道块代替。以“海基一号”深水导管架项目为例，从力学模型、工况分解、强度校核、优化方式几个维度出发，系统阐述了导管架滑移装船用钢制滑道块的设计过程，并应用理论计算结合数值模拟的方式对钢制滑道块的不同受力状态进行了强度校核和优化分析。结果证明导管架装船启动状态为钢制滑道块的最危险受力状态，需要重点关注，而对钢制滑道块前端的结构空腔浇筑混凝土可有效降低内部结构的集中应力，提高结构可靠度。

The development trend of jackets toward large scale and deep water is accompanied by higher load-out difficulties， which poses severe challenges to the performance of slide way blocks located at the quay front. The traditional concrete slide way block is difficult to meet the strength demand， and it needs to be replaced by a steel slide way block with better mechanical properties. This paper takes the deep water jacket project “Haiji-1” as an example， systematically expounds the design process of steel skid way blocks for jacket slippage load-out from the aspects of mechanical model， working condition decomposition， strength check and optimization method. The methodology of theoretical calculations combined with numerical simulations is used for the strength check and optimization of the steel slideway blocks in different stress states. The results show that the load-out start state of the jacket is the most dangerous stress state， which needs to be paid more attention to. The pouring of concrete in the cavity at the front of the steel slide way block can effectively reduce the stress concentration of the internal structure and improve the reliability of the structure.
