| 摘 要： | 含水层中的弱透水层和回灌过程中的堵塞问题是影响地下水人工回灌工程效率和寿命的关键问题.本文通过室内实验,模拟了自然状态地表覆盖有弱透水层的情况下,正常回灌、局部开挖回填砂砾石,以及设计的局部高位入渗方法对渗透池入渗速率的影响.实验证明,实践中通常采用的局部开挖回填砂砾石的方法对入渗效率的提高是有效的,但是由于回灌水源在...

| Abstract: | The aquitard in aquifer and the blocking in recharge are always the key factors to influence the efficiency and lifetime of the recharge project.Based on the indoor tests and under the condition of the aquitard existed,the influence of the normal recharge and the local high-level infiltration to the infiltration rate of the infiltration basin is simulated.The tests show that the local sand gravel filling is effective to increase the hydraulic conductivity,but the blocking on the backfilled surface forms rap... |
