船闸闸首是建筑在岩土地基上的填埋式结构,轮廓形态不规则,各向几何比尺同阶,承受的荷载也较复杂,既有垂直于船闸纵轴线的横向荷载,又有由闸门传来的巨大集中荷载。因此,闸首结构的计算是属于弹性地基上的三维问题。对于这样一个空间结构,日前工程设计中常采用简化的计算方法,即将闸墙与底板分别计算;对于底板,则根据
The lock of the ship lock is a landfill structure built on the rock foundation. The shape of the profile is irregular. The geometrical scale of the same direction is the same order and the loads are also complicated. Both the lateral load perpendicular to the longitudinal axis of the lock and the A huge concentration of load from the gate. Therefore, the calculation of gate structure belongs to three-dimensional problem on elastic foundation. For such a space structure, a few days ago engineering design often used a simplified calculation method, the gate wall and the floor are calculated separately; for the floor, according to
