含水层

Then, basing on the practical problems of the studying area-the thickness of aquifer is little, the capability of depositing water is finite, the Quaternary loose stratum directly superimposes the bedrock strong breeze girdle, the writer thinks it is difficult to answer for the water use of the polyvinyl chloride project by the centralized tube well pumping.

根据研究区含水层厚度小、储水能力差，第四系松散层直接叠加在基岩强风化层之上的具体特点，认为管井集中开采难以满足聚氯乙烯工程的需水量要求，采用集水廊道最大限度地激发河流对地下水的补给，是在这一地区获得较大开采量的有效方式。

Secondly, on the basis of research on construction technique, this paper gave some advice on improvements in condition of underplayed confined aquifer and sand.

在此基础上，结合工程实践针对有打穿下卧承压含水层及普遍存在夹砂层情况下真空预压法施工工艺中各个环节需要改进的地方进行了探讨，提出了一些改进建议。

Firstly, by the data measured from field test, it was analyzed the characteristics and effect in reinforcing soft foundation with vacuum preloading method in which there is underplayed confined aquifer and sand.

首先，总结了真空预压现场试验监测成果，结合本工程有部分打穿下卧承压含水层及普遍存在夹砂层的特点，分析在此情况下，利用真空预压法加固软基的工程特性和效果，为以后类似工程的设计、施工工艺改进、机理研究和数值模拟等提供参考。

According to the structure of terrane and exploring water result of coal floor disclosed by hydrology drill hole,it is demonstrated that there exists strong relationship among abnormal apparent conductivity, crack in rock stratum and the extent of filled water in crack,an.

应用音频电透视技术，分析了杨村煤矿2702工作面底板30 m和50 m深度界面的探测成果，并与井下水文钻孔揭露的煤层底板岩层结构及探水结果对比研究，发现音频电透视探测的煤层底板综合视电导率高异常与岩层的裂隙性及其充水程度具有很强的关联性；岩层裂隙与含水层连通性良好部位明显显现视电导率高值异常，结果表明，音频电透视探测成果能够综合反映底板岩层的阻水条件。

Contaminants can easily enter the subsurface through thin soil cover in stone forest and via swallow holes at the bottom of depression.

究其原因，尽管药池坝洼地底部土壤层覆盖较厚，但存在地表径流集中排向落水洞，生态石林分布区地表裂隙、溶沟发育，可直接接受雨水入渗，因而污染物极易通过降雨和地表径流过程进入含水层。

By taking subinclined shaft construction in Gedian Coal Mine as an example,this paper introduces the pre-injection project and construction of the driving face with strong water-bearing bed .

通过葛店矿暗斜井工程施工实例，介绍了强含水层掘进工作面预注浆工程与施工情况。注浆后工作面涌水量满足了掘进技术要求，在经济、安全、施工速度等方面都显示出较大的优越性，具有推广的价值

The location and extent of aquifers is dependent upon the geological conditions of the underlying rock.

含水层的位置和范围是根据下垫岩石的地质条件所决定的。

Corporations are taking over town aquifers and selling it back to the people for $2 per bottle.
