分洪闸

金山坝作为分洪闸下游阻水障碍时，其破除不会有人为的阻力。

The Jinshan Dam took when flood-diversion sluice downriver anti-water barrier , it eradicates cannot have artificial resistance .

根据大量工程实例，已建成的水闸（包括水库泄洪闸）闸墩和经常暴露于大气中的水闸底板（例如分洪闸）产生裂缝的情况比较普遍。

According to a large amount of engineering example , it is very universal , the constructed dam ( including flood diversion sluice of dam ) and the base plate of sluice , which frequently exposes in the atmosphere ( e.g. flood-diversion sluice ) come into being cracks .
