摘　　要：结合建设在粉砂地基上的"井"字形梁格式底板水闸的结构设计特点,采用ABAQUS有限元法对其闸室的结构内力及其分布规律进行分析。分析结果表明:完建、挡水和过水三种计算工况下,"井"字梁格式底板在横梁与纵梁Ⅱ交叉部位的弯矩值和剪力值最大;桥柱3(4)底部内表面所受的拉应力最大;在不同弹性模量粉砂地基上"井"字形梁格式底板水闸的适应性较好。Combined with the structure design features constructed on jing shaped beam grid bottom board sluice of silty sand foundation,we use the finite element method to analyze the chamber＇s structure internal force and its distribution rules. Analysis results showed that under three kinds of calculation conditions,the bending moment value and shear value of jing shaped sluice gate in the cross site of cross beam and the longitudinal beam II,and the bottom surface of the bridge column 3（ 4） bears the maximum tensile stress. The jing shaped sluice bottom board on silty sand foundations with different elastic modulus of the foundation has good adaptability.
