摘　　要：讨论船闸和水闸内力分布的特点,指出常规底板分析方法对最大负弯矩的估计不足是软基上船闸底板产生裂缝的主要原因。根据京杭运河苏北段复线船闸的建设经验和对皂河船闸闸底板的研究成果,证明了底板分缝施工方案是解决软基上船闸厚底板开裂的一种十分有效的措施。Distributive law of the internal forces of a lock floor on soft foundation isdiscussed, and it is pointed out that underestimate of the maximum negativemoment in lock floor by using conventional analytic method is the principalcause of cracks produced in the lock floors on soft foundation. On the basisof the constuction experience of the second-line ship locks of North JiangsuSection of the Grand Canal and the research achievements on Zaohe Lock Floor,facts have proved that the construction scheme of setting up construction jointsin large floors is an effective way to prevent the thick lock floor on softfoundation from cracking.
