| 中文摘要: |
| 本文分别应用5种数值计算方法，模拟了山东淄博裂隙岩溶水中污染物的运移，结果表明总变异消减法(TVD法)和混合特征线法(HMOC法)求解该类水文地质条件比较合适。为了解影响污染物运移的主要因素，为污染物治理提供依据，文中将数值计算和敏感度分析结合起来。通过大量的计算，找出主要因素是污染源和水井抽水。因此治理的主要策略为在移去污染源的基础上采用水力截获法，且水力截获带的水井位置、间距、深度和抽水量等，必须充分考虑当地的水文地质条件。 |
| 英文摘要: |
| Five numerical methods are applied to simulate the transport of contaminant in fracture-karst aquifer in Zibo City, Shangdong Province, China. The comparison of the simulation results shows that the total variation diminishing(TVD) method and hybrid method of characteristics(HMOC) are more suitable to this type of hydrological condition. In order to find out the major factors influencing the transport of contaminant sensitivity analysis is carried out. It is found that the contaminant sources and well pumping are the major factors. Consequently, the effective measures for remediation are removing the pollution sources and establishing the hydraulic capture zone. In the design of hydraulic capture zone, the location, interval, depth and pumping rates of wells must be carefully considered according to the local hydrological situation. |
