(1)滩地的保留和利用 (1) reservations and utilization of beach land 滩地是山溪性河道的特有产物。一般河道滩地较开阔,洪水期水流漫滩,利于行洪滞洪,应保留其功能,并充分开发利用。流经城区的河道,在维持滩地行洪功能的同时,利用滩地设置绿化地、公园、交通辅道和运动场所,开发其休闲、亲水功能,成为市民娱乐、健身、游玩的好地方。整治中,顺应河势,因河制宜,保留河滩和弯道,恢复河道的天然形态,减少河床的坡降,降低洪水位,减少洪峰压力,同时可降低防洪堤的高度。另外,弯曲的水流更有利于生物多样性,为各种牛物创造了适宜的生存环境。 The beach is a unique product of the mountain stream. Generally, the beaches of rivers are relatively open, and the flood season is full of water, which is beneficial to flood detention and flood discharge, so its functions should be retained and fully exploited. The river course flowing through the city, while maintaining the flood function of the beach, sets green land, park, traffic auxiliary road and sports place by using the beach land, and develops its leisure and hydrophilic functions, and becomes a good place for the citizens to enjoy entertainment, fitness and play. In the course of regulation, the river regime is adapted to the river conditions, the river beach and the bend are retained, the natural form of the river is restored, the slope of the river bed is reduced, the flood water level is reduced, the flood peak pressure is reduced, and the height of the flood embankment can be reduced. In addition, the curved water flow is more conducive to biodiversity, creating suitable environment for all kinds of cattle. (2)复式 断面的设计 (2) the design of compound section 山溪性河道一般河滩开阔,河道断面设计可采用复式断面形式。枯水期流量小,水流归槽主河道;洪水期流量大,允许洪水漫滩,过水断面大,洪水位低,一般不需修建高大的防洪堤。枯水期根据河滩的宽度和地形、地势,结合当地实际充分开发河滩的功能:如滩地较宽阔,一般可开发高尔夫球场、足球场等大型或综合运动场;河滩相对较窄的可修建小型野外活动场所、河滨公园或辅助道路等。河滩的合理开发利用,既能充分发挥河滩的功能,又不因围滩而抬高洪水位,加重两岸的防洪压力。 Mountain river channels are generally open, and cross section can be used for river section design. In the dry period, the flow rate is small and the water flow to the main river channel; the flood discharge is large, the flood floodplain is allowed, the cross section of the water is large and the flood level is low, and the large flood embankment is not needed. In the dry period, the function of the river beach is fully developed according to the width of the beach and the topography and terrain, combining with the local reality. If the beach is wide, the golf course, the football field and other large or comprehensive sports fields can be developed. The relatively narrow riverside can build small field activities, riverside park or auxiliary road. Reasonable development and utilization of river beach can give full play to the function of river beach, without raising flood level due to beach enclosure, and aggravate flood control pressure on both sides.
