Study on immersion area of the Liaofang hydranlic engineering project;

廖坊水利枢纽工程浸没范围研究

Xixiayuan reservoir,a plain reservoir, will bring some immersion to the areas of the lower reaches of the dam, the dam with or without antiseepage measures will create different effects on immersion of lower reaches of the river.

西霞院水库作为平原型水库 ,水库蓄水后会造成坝下游部分地段浸没 ,并且大坝有无防渗措施对下游的浸没影响很大 。

The second variation formula of vertical energy functional for a submersion between Riemannian manifolds is calculated with a simple and direct manner.

对于黎曼流形的浸没建立了垂直能量泛函的二阶变分公式,研究强垂直调和映射的稳定性。

As the water level in the reservoir of Chaozhou water supply project is generally higher than ground surfaces on both banks when the reservoir is filled up,the city and the farmland along the riversides may be immersed in groundwater.

潮州供水枢纽工程库水位普遍高于两岸,水库蓄水后,可能对两岸城区、农田造成浸没影响。

The important technical problem of submergence evaluation for the right bank of down stream of the subsidiary dam in Nierji irrigation works was solved.

在三维渗流电网络计算的基础上,进一步进行了粘土层内含水带的埋深计算,并重新选定毛管水上升高度值和浸没临界深度。

Aiming at the irresolvable limitation of the infiltration recharge and evaporation from the upper boundaries of the submergence prediction, this paper has established a mathematical model for transient flow based on groundwater simulation software Visual Modflow, which takes account the conditions of recharge and evaporation for the analysis of effect of submergence on the nearby farmland.

针对浸没预测忽略上边界入渗补给和蒸发等问题的缺陷,利用VisualModflow地下水模拟软件,建立了非稳定流数学模型,设定合理的边界条件,重点探讨了入渗系数和蒸发系数的确定方法和步骤。
