摘　　要：本文对漫湾弧形闸门作了三维有限元应力计算,并给出了弧门控制点处的位移和应力。计算结果表明,象漫湾闸门这样的大型弧门结构,只按照闸门规范制订的平面体系来进行结构计算是不够的,其计算结果已不再偏于安全。文中对空间有限元计算结果做了分析,并和平面体系的手算结果作了比较,并依此说明现行规范中的结构计算所存在的缺陷。Based on 3-D finite element technique, stress analysis of Manwan radial gate is developed in this paper, and the values of displacements and stresses at the gate's crucial points are presented, which show that for large-scale radial gate structures such as Manwan gate structural calcu-lation based on the Gate Designing Standard is not sufficient since it no longer provides a secure result. The values obtained through the finite element method are discussed and compared with those of plane system, from which the drawback existing in the structural calculation of the present Standard is pointed out.
