摘要
在设计阶段针对潮州供水枢纽工程对潮州城区的浸没问题进行数值分析,对城区的水头分布情况进行预测,并在各个可能受浸没影响的区域布置地下水监测网络,对地下水进行长期监测。整理前期数值计算成果,结合蓄水2 a多来地下水测点的实测资料及现场调查,对城区浸没情况进行分析评价,结果表明:原设计目标基本实现;根据地下水实测资料可将城区按受蓄水影响和减压井影响程度划分为3个区域,潮州主城区位于同时受蓄水及减压井影响范围内,浸没影响范围在堤后600～1 000 m范围内;减压井的工作效果较好。
During the design stage of Chaozhou water supply pivot project, the immersion problem is analyzed and the waterhead distribution is predicted. Groundwater monitoring network has been laid out to monitor the groundwater in the area that may be affected by immersion. Based on the previous numerical analysis results, combined with a more than two-year groundwater monitoring data and field investigation, the immersion is carefully analyzed and evaluated. The result shows that the primary design goal has been basically realized. According to impoundment and surge shaft influence degree of the groundwater monitoring points, the city zone is classified into three typical areas and Chaozhou main city zone is in the area affected both by impoundment and surge shaft. The immersion affected area is within 600- 1 000 m behind the dike and the surge shaft works comparatively well.
