On the plain area, reservoir is in depression, lakes such as foundation, through these depressions, lakes and buildings around the gate control, embankment to constitute a reservoir. 水库的防汛作业必需要顾及到上游和下流两方面。为了保证水库上游居民的生命和产业不受要挟，必需要加强对水库内的蓄水高度办理，严厉束缚其高度，保证其在安全的规模之内；水库泄洪量的巨细要视下流的河道实践的状况而定。假如在一个流域中建有多个水库，就必需要加强彼此之间的协作运用，使其可以发扬干流和支流错峰以及抵偿调理的效果。水库不光要可以及时的调整库容来寄存洪水，还必需要具有可以长时间坚持定量的需水量的才能。总而言之，在防汛的关联作业中，水库既要统筹上、下流，还要对一部分洪水施行阻拦并将其转化为可供运用的水资源，供大家的平常日子、生产活动运用。 Reservoir flood control operation will need to take into account the upstream and downstream two. In order to ensure the reservoir upstream residents life and industry is not threatened, must strengthen the reservoir storing water in the high management, strict constraint to its height, ensure the safe scale; the size of the reservoir flood discharge to river downstream of the situation and practice. If in a basin with a reservoir, you will need to strengthen collaboration with each other, so that it can carry forward the main stream and tributaries of the peak and offset the effect of the conditioning. The reservoir will not only can be adjusted in time to register the database of flood, also need to have long time adhere to the water required for quantitative ability. To make a long story short, the associated operation of reservoir flood control, to co-ordinate, dirty, but also on the part of the implementation of block flood and transformed into available water resources, available for everyones daily life, production activities using. 河道可以有用的发泄洪水。在平原区域，必需要不断地加强河道泄洪才能，只要这样才可以有用地避免洪水、发泄洪水。要想进步河道的泄洪才能就必需要构筑堤防。水利工程中的当地可以发扬如下效果：束缚洪水，维护两岸的大家生命和产业以及工农业生产不会遭到洪水众多的损害；对水流进行束缚，进步河道泄洪与排水才能；反抗风波和海潮，避免其对陆地的侵袭。关于堤防来说，其在建造时必需要和河道的整治作业紧密结合。 Vent flood channel can be useful. In the plain area, need to continue to strengthen the channel to release flood waters, as long as it can effectively avoid flood, flood vent. In order to release flood waters to progress the river will need to build dikes. Water conservancy project in the local can develop the following effects: bound flood, safeguard cross-strait people life and industrial and agricultural production will not be flood damage; bind on water flow, river drainage to release flood waters and progress; against the storm and tide, avoid the land invasion. On the dike, the building will need and river regulation work closely with. 管涌就是咱们常说的下流坝脚周边土地上出现冒出细砂等的孔状出水口或部分土体出现拱起状况等。关于这样的表象来说，常选用的抢险办法主要为反漏压盖法：榜首，要保证敷设的规模内没有杂物；第二，在管涌的附近铺设20 cm厚的粗沙；第三，在粗沙层上铺设20 cm大、小石子各一层；第四，要放置石块进行维护。这样能有用的避免由于管涌而形成险情。裂缝的抢险办法，关于裂缝的抢险办法，一般运用的是开挖回填。 We often say that the downstream piping is toe surrounding land appears out of sand and other porous outlet or part of soil arch appears status. On such a representation, the emergency measures against leakage mainly gland method: first, to ensure that no debris laying scale; second, the laying of 20 cm thick and coarse sand in the piping nearby; third, the laying of 20 cm, small stones each layer in the coarse sand layer; fourth, to the
