| 摘 要： | 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。在大量的勘测、观测、调查工作的基础上，对库区蓄水后的地下水渗流场进行分析，对各种可能的工程措施进行计算比较，并提出合理且切实可行的工程方案。

| Abstract: | 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. On the basis of numerous investigations and observations,seepage field of the groundwater in multiple aquifers is analysed with a FEM program with a two-dimensional seepage model in the horizontal plane with a multi-layer medium approach. The outcome reveals that the regions behind levees are mostly influenced by the rising groundwater level,especially downtown behind City Levee. Also,it shows that the anti-seepage curtain gives help to lower the groundwater head obviously in the zones protected by Dongxiang and South Levee except downtown behind City Levee where relief wells or filter drain shoud be adopted in addition. The effects of such wells with various head level and space intervals are calculated to provide options for practice and a suggestion is proposed that water head in the wells during flood need to be raised to prevent extreme discharge. In addition,if conditions permit,filter drain is more effective than the well and easier to maintain. |
