本文研究了一种适应大管桩基础和大跨度要求的码头新型上部结构──钢筋混凝土微折板。通过大量的平面、空间有限元计算，较深入地研究了微折板的力学机理，为它的推广和应用提供了理论依据。基于平面有限元计算，提供了一套确定微折板内弯矩和拱推力的影响线表，并提出了考虑微折板空间性质的实用计算方法的建议。

The steel fiber concrete slight fold plate, a new type wharf superstructure on large pipe pile with large span foundations, is studied in this paper. Extensive 2-D and 3-D finite element computation have been performed. That gives an insight into the mechanism of foe slight fold plate and provides a theoretical basis for its development and application in engineering practice. By means of 2-D finite element computation, a set of tables are presented for the determination of bending moment and arch thrust in slight fold plate. Moreover, some practical recommendations in which 3-D property of the plate is taken into consideration are given.
