高桩码头门机梁的设计一般采用刚性支承连续梁计算法。在设计南京港高桩码头门机梁时,发现按刚性支承连续梁和按弹性支承连续梁计算所得弯矩和支座反力,两者相差甚大,而前者使梁的配筋很不合理并增加了基桩长度,很不经济。为此,采用了弹性支承连续梁法计算。众所周知,按弹性支承连 The design of the portal beam of the piled wharf generally adopts the method of rigid support continuous beam. When designing the machine beam of Nanjing Port piled high-pile wharf, it is found that the bending moment and the bearing reaction force calculated by rigid continuous beams and elastic continuous beams are quite different, but the former makes the reinforcement of the beams very unreasonable Increase the length of the pile, it is not economical. To this end, the use of elastic support continuous beam calculation. As we all know, according to the elastic support even
