Protection method for park outside embankment
The invention relates to an out-of-dam park protection method. The method comprises the following steps that out-of-dam park data and river channel information are collected; constructing a model according to the data of the park outside the levee and the river channel information, the model being used for simulating the water flow velocity of each area of the park outside the levee during flood; according to the data of the park outside the embankment and the river channel information, the maximum permissible scouring flow velocity of each area of the park outside the embankment during flood is calculated; determining a scoured area according to the water flow velocity and the maximum allowable scouring velocity of each area of the river channel; a protection facility is arranged in the scoured area; the protection facility is a sandy gravel flow guide body; a tidal river channel beach protection structure is arranged on the middle and lower stream beaches of the park outside the embankment; according to the river regime power, a riprap flow guide body is arranged on the upstream or downstream of the tidal river channel beach protection structure. According to the method, the water flow velocity of each area of the park outside the embankment during flood is calculated through the model, the water flow velocity of each area is compared with the maximum allowable scouring velocity, the scoured area is determined, and the protection facility is arranged to reduce scouring of the park outside the embankment.
本发明涉及一种堤外公园防护方法，包括以下步骤：采集堤外公园数据及河道信息；根据堤外公园数据、河道信息构建模型，模型用于模拟洪水时，堤外公园各区域的水流流速；根据堤外公园数据、河道信息计算洪水时堤外公园各区域的最大允许冲刷流速；根据河道各区域的水流流速和最大允许冲刷流速确定受冲刷区域；在受冲刷区域设置防护设施；防护设施为砂卵石导流体；在所述堤外公园的中下游边滩设置感潮河道岸滩防护结构；根据河势动力，在感潮河道岸滩防护结构的上游或下游设置抛石导流体。本发明通过模型计算洪水时堤外公园各区域的水流流速，将各区域的水流流速与最大允许冲刷流速进行对比，确定受冲刷区域，并设置防护设施，降低堤外公园的冲刷。
