摘　　要：从计算思路、计算过程等方面详细介绍了现有高强预应力混凝土板桩的两种抗裂弯矩计算方法,将板桩生产企业采用的抗裂弯矩计算方法和钢筋混凝土规范(GB50010-2010)的计算方法进行对比,分析了两种算法特点及适用范围。通过试验和工程应用进行验证,得出两种算法在计算思路、过程及结果上的差异和产生差异的原因,为高强预应力板桩的设计和发展提供了新思路。Two methods for calculating crack-resistance moment of the pre-stressed high-strength concrete sheet piles were introduced in detail from their ways of thinking and calculation process. The method adopted by sheet pile manufacturers and the one adopted in the Code for Reinforced Concrete （GB50010-2010） were compared for their characteristics and application scopes. Compari- son results were verified through tests and field applications. Differences in the way of thinking, processes and results were pointed out as well as causes of such differences. A new way of thinking for the design and development of high-strength pre-stressed sheet piles was put forward.
