摘　　要：根据大型多纵梁矩形渡槽槽身结构及其横向受力特点,提出了"弹性支承连续梁"法进行横向受力计算,使复杂的空间结构计算得以简化.计算时,底部弹性支承在各纵梁上,可求得结构的横向受力与弹性支承反力.并根据力法位移协调方程,给出了三梁式和四梁式渡槽横向结构弹性支承反力的计算公式.通过南水北调工程中某大型渡槽的计算分析,表明此方法方便、合理,有很大的实用价值.The elasticity support continuum beam method is brought forward according to orientation structure endure force character of large rectangle aqueduct with multi-longitudinal beam. The method makes complicated space structure calculation simple. The bottom structure is supported by every longitudinal beam in orientation calculation, and then the orientation force and elasticity supporting force is obtained. Calculation formula of orientation structure elasticity supporting force is given .The method is proved to be convenient and valuable through example calculation and analysis about the South-North Water Division Project .
