黄河下游沿黄开采地下水干扰抽水试验研究

Experimental Study on Pumping of Disturbance of Groundwater Exploitation along the Lower Yellow River

为确保沿黄长期开采地下水条件下黄河大堤和城市供水的安全，在开采区的石桥进行了大型干扰抽水试验，结果表明：修正后的降深干扰系数在井距300m时为12％，井距500m时为6％；黄河大堤下的土体最终压密量是13．50～22．23cm，开采沿黄浅层地下水所诱发的地面缓慢沉降不会对黄河大堤造成危害。

It conducts a large scale disturbance pumping test in Shiqiao of exploitation area for guaranteeing the security of urban water supply and the embankments of the Yellow River under the conditions of exploiting groundwater along the river for years.The outcomes show that the slow settlement of ground surface introduced by shallow groundwater exploitation along the Yellow River could not endanger the embankments when the revised depression head coefficient of disturbance as well spacing 300 m is 12%,6% as well spacing 500 m and the final soil compaction beneath the embankments 13.50 ~ 22.23 cm.
