位于山前冲洪积倾斜裙上的长距离输水渠道,渠线上下游分布着公路、铁路及已有灌区,如何结合公路、铁路及灌区现状选择布置沿线防洪系统和防洪建筑物形式,是工程总体布置中的难点问题之一。在此根据北疆某干渠防洪系统的布置和措施,谈谈长距离输水渠道防洪布置应注意考虑的问题,供大家在今后长距离输水渠道的总体布置中加以借鉴。
The long-distance water conveyance channel located on the front alluvial slope inclined skirts is divided into highways, railways and existing irrigated areas on the upper and lower reaches of the channel. How to arrange flood control systems and flood control structures along the existing status of roads, railways and irrigation areas? One of the difficulties in the overall layout of the project. Based on the layout and measures of the flood control system of a trunk canal in the northern part of the country, we should pay attention to the issues to be considered in the flood control layout of long-distance water transmission channels for reference in the overall layout of long-distance water transmission channels in the future.
