摘　　要：根据板壳理论中集中荷载与均布荷载作用下四边简支板的重三角级数解,按照变形等值和弯矩削峰内力等值原则确定双向板等效荷载,据此编制程序,分析板跨变化对等效荷载值的影响,找出两种计算方法确定等效荷载取值的变化规律,据此合理布置板跨,达到安全、经济的目的。According to the four sides non -fixed plate＇s retriangle series solution on plates and shells theory, determined equivalent distributed loads value on curving pare peak and deforming on plates carried by both directions. Programming on the grounds, analysized effect on the equivalent loads value arise from the chang on across ratio, found the regulation of the equivalent distributed loads value from above two methods. Therby,determinined the plate arross arrange to attain safety, economy purpose.

关 键 词：集中荷载 双向板 弯矩削峰 变形等值 等效荷载 比较
