在水闸设计中,为了节约三材,江苏等省广泛地采用了反拱底板结构形式,利用拱内应力主要是轴向压力这一特点,使底板厚度减薄,底板内钢筋用量减少,甚至于在底板内基本上不配置钢筋,这种结构形式与整体式闸底板相比大大地节约了钢筋与水泥的用量。反拱底 In the sluice design, in order to save three materials, Jiangsu and other provinces widely adopted the form of inverted arch floor structure, the use of arch stress is mainly the axial pressure of this feature, so that the thickness of the floor thinning, reduce the amount of steel rebar, and even in the Basically, no rebar is arranged in the bottom plate, which greatly saves the amount of steel and cement compared with the integral sluice floor. Anti-arch bottom
