| 摘 要： | 工程开挖及建成后对含水层结构的改造,无疑会对开挖区周围地下水造成影响。利用数值模拟方法分析预测某水利工程尾水渠开挖及建成后周围地下水水位的变化。预测结果,大开挖后周边地下水位将快速降低,且不同地段水位降幅不同,右岸阶地内水位降低约0.26~7.26 m,工程建成后,阶地内水位将逐渐恢复,但相比施工前水位仍降低0.09~0.38 m。分析水文地质结构,合理概化,建立数值模型,对于分析工程开挖对地下水的影响,是种有效方法。

| Abstract: | The excavation and completion of a project changed the aquifer structure, and it will have an impact on the groundwater around the excavation area. Using numerical simulation method to analysis and prediction the water level changes of a tailrace project when construction and completion. The results show that, the underground water levels will quickly decrease after the heavy excavation, and water levels fall different in different region, the underground water levels will lower 0. 26 - 7.26m in the right terraces. After the project is completed, the underground water levels will gradually recover, but it still lower 0.09 - 0.38m than before. For analysis of hydrogeological structure, reasonable generalization to establish numerical models, analysis of excavation effect on groundwater, it is an effective approach. |
