摘　　要：采用常规设计方法和有限元法对坞式闸室结构进行计算比较，并结合一些船闸的实测资料，指出常规设计方法对结构底板的负弯矩估计不足是导致底板开裂的主要原因。In this paper, the U-frame lock structure has been analysed and compared with conventional analytic method and finite-element method, according to the measured data,it is pointed out that underestimate of the maximum negative moment in lock floor by using conventional analytic method is the principal cause of cracks pnduced in the lock flooron soft foundation.
