摘　　要：采用葛氏法查表计算船闸坞式结构时,要将闸墙所受荷载简化到底板上,通过不同荷载简化方式的计算,并与有限元方法计算结果比较分析,认为传统荷载简化方式无论从结构力学的角度,还是从计算结果的合理性来看,均存在一定问题,针对不同的坞式结构特点,推荐了相对较合理的荷载简化方式。The load acted on the lock wall should be simplified on the floor when the Ge＇s table lookup method is utilized in the structure calculation of the lock＇s dock. This paper makes calculations of different load simplified methods, and compares the results with the calculation results by the finite element method. It is indicated that the traditional simplified methods exist some problems in the view of structure mechanics and the reasonability of calculation results. Rational simplified methods of calculation load are recommended according to characteristics of different dock structures.
