摘    要:钢筋混凝土双悬臂式结构闸室自重轻、造价省、应用广泛,但在施工期回填土某段时间内地下水的浮托力可能超过结构自重加回填土压重;或是地下水的倾覆力矩超过闸室墙后水土压力的平衡力矩,从而导致整个闸室结构的破坏。因此,必须进行施工期的稳定计算,并采取相应压重措施以确保闸室结构施工期的安全。

关 键 词:双悬臂式  闸室  施工期  稳定  压重

Abstract:For the steel reinforced concrete double-cantilever structural gate chamber, its self-weight is light, its construction cost is saved and its application is widely, but the floating power of underwater in some section of time when the backfilling of the construction period maybe exceed the self-weight of structure plus the pressure weight of backfilling or the overturning moment of underwater will exceed the balancing moment of water and soil pressure at the back of gate chamber wall so as to result in damaging the whole gate chamber structure. Therefore, it must be to carry out the stability calculation of construction period, and the relative weighting measures are taken to ensure the safety for the construction period of the gate chamber structure.
Keywords:double-cantilever  gate chamber  construction period  stability  weighting
